Chose Microsoft Teams
Our company used to use Skype for Business and for a short time, we used Slack. We've been using Teams for over a year now and it has surpassed both of those tools. Audio calls over Skype always had technical difficulties and sound issues, though screen-sharing worked pretty …
Chose Microsoft Teams
Teams is better and better every day. I still don't think it's to Slack's level but it still has so many great features, especially if you're an existing Office/outlook user. It integrates well with Office 365 applications and also other 3rd party apps.
Chose Microsoft Teams
I enjoy Teams better than Lync/Skype for Business, but I enjoy Slack the most for inter-company communication and UI/UX convenience. The learning curve for Slack is very small and it has a casual atmosphere that would engage the employees in a more fun and welcoming manner than …
Chose Microsoft Teams
Although competitors such as Slack and Webex can really stand up to MS Teams, our organization chose Teams as the predominant work communicator. Working within this decision, we are overall happy with the feature set that Teams provides. In my opinion, the advantages of its …
Chose Microsoft Teams
I do not use Microsoft Teams if I can avoid it, because I can get the same type of work done in Slack, which has a much more intuitive user interface and is more modern in terms of functionality. I also use Skype for Business more regularly because it uses fewer computer …
Chose Microsoft Teams
Teams has very similar virtual meeting capabilities to Zoom, however it can sometimes lack in connectivity reliability compared to Zoom. It also lacks some key features vs. Zoom, such as the ability to manage breakout rooms multiple times in the same meeting invite.

Compared to S…
Chose Microsoft Teams
Microsoft Teams is becoming the norm for a lot of companies. I can't say that it beats Slack in every respect but, from my limited experience with Slack, I would say Microsoft Teams is initially easier to use and understand. When it comes to integrations, however, Slack still …
Chose Microsoft Teams
MS Teams is the worst as compared to other tools in the market. Slack, Discord are way way better than MS Teams. I believe way more advanced than MS Team could ever achieve. I am really not sure how this trashy and buggy tool manage to get 8/10 on this platform. Shame.
Chose Microsoft Teams
I prefer using Slack for text and quick video/audio calls. It is easy and has features like GIFs and other integrations built in. It's a nice one button way to communicate. We use Zoom for our more structured meetings and I use Zoom for my training sessions because I can plug …
Chose Microsoft Teams
I only use Teams because I am forced by my employer. I think Slack is far superior - it just works.
Chose Microsoft Teams
We chose primarily because of the promised integration with the Microsoft Business Suite - which it mostly delivers on. That does give Teams an obvious advantage over competitors. IMHO Teams has a richer, more mature feature set, and the experience is more reliable and stable. …

Microsoft Teams is more intuitive, clearer to use, and has more in-depth features.

Microsoft Teams is faster and very responsive when compared with those tools. Also it is robust and does not crash. It is compatible with most of the OS and platforms. Backward compatibility is amazing. It is an enterprise tool. So can be efficiently used for both client …
Chose Microsoft Teams
Teams have more features and more efficient. we can rely on it without any fear of interruptions or unexpected behavior.
Chose Microsoft Teams
The only reason of use of Microsoft Teams was its price, which was smaller that the price of competitors. But despite the lower price, Microsoft Teams supports fewer functions and provides less quality.
Chose Microsoft Teams
We actually never asked to purchase Microsoft Teams. We got it within our Office/Microsoft 365 subscriptions. We were using Skype 4B within Department and when Teams was announced, within a week or two we tried to use Teams on Department level.
Within first 6 months people …
Chose Microsoft Teams
Teams is nice because of the Microsoft integration.
Slack
Chose Slack
Slack has a great layout which makes it very user friendly. It is quite similar to Microsoft Teams and equally just as good. Better than Whatsapp Web as a stand alone app, so it doesn't have to be linked to your phone. The colors and fonts are welcoming as well.
Chose Slack
I think that Microsoft Teams is really not good at doing its purpose in any case The UI is unclear, its sometimes full of bugs, it remids me of skype 15 years ag Teams is also a bit laggy
Overall there is nothing that teams do better than Slack in my opinion
Chose Slack
Slack complements our current technology stack. We use Microsoft products for most tasks, but we have found Teams and Slack to be more user-friendly and reliable than Microsoft Teams. It is easy to manage and add/remove users. It is easy to search and find answers to questions …
Chose Slack
More intuitive and user friendly interface. It has better third party integrations with Google Drive, Jira etc. Slack is designed for professional teams rather than gaming or casual communities. Better organization with channels, tread and workspaces. It has more of business …
Chose Slack
In the team, we don't have thread options. Slack does offer thread options, and it is handy to use threads. Discord sometimes gets complicated for a non-techy, whereas Slack is a very easy-to-use platform. I still feel Google Meet and video calls are better and easier to use …
Chose Slack
Surpasses all of these in terms of features and integrations provided. Does a lot more than just internal chats. Way more organization and ability to host a ton of different channels and spaces. Incredibly responsive.
Chose Slack
Slack is more modern than the competitors, and It's designed a lot better than the others. With last releases teams has rebuild the app on a different framework trying to fill the gap, but Slack is still better, for usability, interface and integrations. Teams is only better …
Chose Slack
Slack blows Teams out of the water with its simplicity and fun vibe. I used to work with a team before, but Slack is faster, smoother, and more intuitive—no clunky menus or endless clicks. It is also packed with playful features like custom emojis and integrations, making work …
Chose Slack
Better in every way than teams. Far more intuitive, works without any glitches, more well thought out.
Chose Slack
Slack has a far superior UI that makes information easier to find and use. It has better organizational features across the top to organize content. Slack is constantly evolving with new features, while Teams is slower to roll out anything new.
Chose Slack
We selected Slack because we are based on Google Suite and not Microsoft. It was a clear choice for us but it has been great using Slack because of the versatile integrations with Gmail and Google Drive. It is quick and easy to link to shared files and documents. Also, I feel …
Chose Slack
Much simpler and more pleasant to use than the alternatives.
Provides integrations, with external services, that work out of the box which is often an Achilles heel of competitive solutions.
Pricing is unfortunately not that great when compared to alternatives that come in a …

Slack is much better to use than the alternatives. It provides rich communication methods with better integrations, threads and attachments. It's also seamless when adding people or modifying a group, which is so common in day to day communications.
However I would say the …

My company selected Slack and my previous company too. As Enterprise architect this tool is perfect to me. It goes straight to the point, it's fast, it's light and clear on the purpose. You can prepare your message without anoying others. You can format your text with enough …
Chose Slack
Slack is vastly easier to use than Teams and far less convoluted. It also handles Trello and GitLab integrations in a way that is easy to read and digest (whereas Teams handles them in the most useless way possible). Every time I use Teams, something is broken or I can't find …

Slack has the best features and interface as compared to all other similar software that I have used. Features like huddle, channels, conversations, integrations, polls, and surveys make it better than other similar tools. The mobile application of Slack is also smooth and …

The most convenient way to organize and follow thread (so any conversation) and a very large way to customize the workspace by individual (my workspace is organize in my way, but my colleague can have their own structure and organization). Also being able to add customized …

Ease and usability. Although some have similar features, I find Slack easier and with a user-friendly design.

Positive: The virtual workspace created for a work team within the same company, for the resemblance of information and communications in one place.Negative: The access for members of a non-profit organization who have external emails from the host but need the same access as an internal person since their volunteer work is part of the very core of the federation.

Slack is well suited as another tool in our toolbelt to find answers to common questions and to find resources. it is less appropriate to be used to collaborate on a project in terms of being a project management tool

Pros
Microsoft
  • Virtual meetings - ease of set up and execution
  • File sharing! We build channels for projects, and being able to invite only project members is huge!
  • Peer-to-peer communications - being able to "ping" one of my colleagues, either text, video or call-only, on-demand, is what runs our business.

  • Can create channels for small, medium, or even bigger team to relay important information/updates and whatnots.
  • You can do one-on-one (huddle feature) if you're on-boarding a member.
  • A platform that can be collaborated with other platform. Example a CRM to be linked with Slack for easier comms relay.
  • The best feature for me so far is that you can mention a team member so he/she won't missed an important message you sent.
  • You can directly message about anyone within the company.

Cons
Microsoft
  • The feature of notifications in the mobile application could be improved. Sometimes notifications of different teams are not visible and are only visible when the application is opened.
  • It uses lots of computational resources while running and thus, slows down the system sometimes.
  • It allows a few channels per team. The number of channels could be increased for better productivity.

Salesforce
  • Undoubtedly Slack’s search function is powerful but sometimes it is difficult to find specific messages or files in very active channels with high message volumes. This needs an improvement.
  • I have experienced notification issues on my phone. I am not receiving notifications and have missed important updates as a result. I tried uninstalling and reinstalling the app, but the problem still persists.
  • The Business Plus plan does not include support for data loss prevention or offline backup providers.

Microsoft Teams is included with our Office 365 subscription and we have no intention of migrating off of Office 365 and Microsoft products.

Slack is wonderful, it is a tool that changed our perspective and our way to work. We used to use another one, which was purely and sorely designed to messages. Slack provides us that possibility and more, all the other functions that we daily use in our work routine, not to mention the fact that Slack has a wonderful design and it's really easy to use and adapt.

Usability
Microsoft
User experience has been much better than the previous Skype for Business app. It has an easy-to-use interface with persistent chats. The search feature is very fast and useful. MS Teams has mostly focused on Collaboration and team building features which are very useful for organizational communications. Since Teams is accessible from multiple platforms like Laptop, Desktop, Mobile phones, etc it has been very convenient from a Mobility perspective.

Slack is a soft app, we don't have many issues with it. I recall one or two people complaining about something during our usage period, but I didn't have a bad experience. When the app is slow, usually the problem is with my computer or my internet. The app works just fine.

Using Microsoft Teams has resulted in much faster business communications with both co-workers and consultants. There has been little need for support with this software as the interface is very intuitive and the product is overall very well designed. We did encounter an issue with the built-in phone service, however, this was quickly resolved by the support team.

I've never had to contact support for Slack which is a great testament to its ease and use. Adding people outside of the organization takes a little getting used to, but ultimately allows for greater collaboration between FTE and contractors. There is no clear alternative to this software, so it's the best we can do for now.

Alternatives Considered

Our company and IT department previously used Skype for our communication needs. Skype was not dependable in my opinion, because it seems each time I used it during a call and/or a meeting, I and several other team members would get disconnected more than once. This caused a great interruption of our meeting, caused team members to have to ask others to repeat themselves and caused a general lack of interest in employee attendance during meetings.

Slack is vastly easier to use than Teams and far less convoluted. It also handles Trello and GitLab integrations in a way that is easy to read and digest (whereas Teams handles them in the most useless way possible). Every time I use Teams, something is broken or I can't find things. But Slack is on the ball. Always easy to use and to search. Plus better emoji syntax (um, Microsoft, people put stuff in parenthesis all the time; that doesn't mean they want it to be emojis). Anyway, I'd choose Slack over Teams any day, if given the option.

Honestly, this tool is worth every penny. Yes, it's not free and you pay for the quality of services and the license. But the ROI and the benefits are all there. Also, the renewal, negotiation, and contract terms are all very well explained by our Microsoft account manager, and she's a charm.

Return on Investment
Microsoft
  • I'm not sure I can point to a specific ROI, but it has improved our ability to communicate and work more effectively together.
  • It's also nice to have records of every interaction, photo, and document that has been shared. Less chance of something completely disappearing.
Read full review
Salesforce
  • I don't have hard numbers, but I can't imagine the level of mistakes that would go uncaught without the easy ability of multiple people being alerted to look at something in real time.
  • Efficiency of communicating this way takes a lot of slog out of email, more focus on more important conversations and tasks
  • It is on managers to define expectations on how long it should take someone to respond on Slack; it can feel immediate, which can be distracting to deeper work
