I love slack and the functionality it has! However, it lets itself down that you can't have client meetings through it / need to use another app like google meet for the meetings. It just is more apps/logins needed for employees = time that could be used doing other things.

Chose Microsoft Teams
Breakout rooms are a very good feature that should be added to the platform. Google Meet ranks above Teams on the web, as it's pretty lightweight; Teams tries to do so much, making it very slow or unstable when just using the web version. Teams is superior to Zoom when it comes …

Chose Microsoft Teams
We use both Slack and Teams. We use Slack for most internal meetings and chats. We only use Teams because our larger company requires it, and many of our external customers already have it installed. If we could get customers to use Slack, we would drop Teams in a heartbeat. If …

Personally, I believe that Microsoft Teams stands tall against all of its competitors. What I value most that it brings ahead of its competitors is its options for customization; the modern look and feel of its user interface; the security that it exemplifies; and its …
Chose Microsoft Teams
I think Teams is closest to Slack but much more ubiquitous and also much more user friendly. I do think products like Webex and Zoom seem to have a little more preference for large scale meetings and it's based mostly on reliability and usability. In addition, Teams tie it …
Chose Microsoft Teams
Teams has been a better experience and also has less security concerns.
Chose Microsoft Teams
The advantage of using Microsoft Teams over Zoom is that Teams seamlessly works with Outlook Calendar, Outlook Email, Lists, Forms, etc. If I create a Zoom meeting, I will have to do twice as much work. Working at a Microsoft 365 organization, it is more convenient to use a …

The two products are similar. Zoom has its place in the workplace. It is different from Microsoft Teams. It is more useful for personal use in our environment. Most outside organizations and individuals will have the capability to obtain the product and connect with an entity …
Chose Microsoft Teams
Zoom was the first virtual web program I used, and I still use it for some parts of my job, but I like how chat is included with Teams. Our whole department isn't in the same building, so it is convenient to send a message instead of picking up the phone or even just sending an …

UI is so much smooth to use. As we have to use this collaboration tool daily for connecting with team members Microsoft Teams give mor smooth experience. Everything is categorized on different tab, chat, teams, calander, calls. We can easily navigate through out the …
Chose Microsoft Teams
Microsoft Teams is better than both Zoom and Google Meets to me. It seems to have the functionality of both these platforms and also that of Slack for internal messaging. It's more of a "one-stop-shop" for both these needs which makes it a handy piece of software for use in the …
Slack
Chose Slack
Slack was more of a company directive. Teams has its strengths. But Slack definitely seems more mature in terms of features that engineering teams love. Video conferencing is much better in teams.
Chose Slack
I think it stacks. I haven't seen those products in the last few years, but I feel like the way Slack has evolved and how much integration it has with Salesforce. I don't think any of the other tools I've seen do that.
Chose Slack
In my opinion, the closest to Slack in terms of UI is Discord. But Slack is much more professional with more functionalities that doesn't require very technical knowledge (good for our older staff who began their digital journey within the last decade). In terms of workflow …

better price and less spam with Slack. It was the best decision to switch to this communication platform for our company. We would do it again if given the opportunity.

Teams has an edge over Slack as teams is also a meeting platform Copilot by teams is very well integrated tot eams making it super easy to use AI without extra steps and additional integrations Teams is also great with long messages / rewording messages and any vocabulary …
Chose Slack
The other platforms have valuable features (like progress kanbans and storage for big files) but none of them work on their own. Slack is the central hub that we use for all communications, discussions, and meetings.

Slack excels at versatility and ease-of-use. Everyone knows …
Chose Slack
In comparison to Teams, I think Slack is a much nicer platform to use. If your technology department allows you to integrate third party applications, it can work really well paired with zoom, sharepoint etc. I think for many mid sized businesses it can be a good fit to enhance …
Chose Slack
Slack is better suited for actual work teams rather than communities, so it wins against Discord. About HipChat - in my opinion, it was a dinosaur that is not discounted, and it's obvious why, considering the type of product Slack delivered!
Chose Slack
From a corporate standpoint, I don’t really have another example. On a personal level, the closest comparisons would be WhatsApp, Messenger, or KakaoTalk. To me, it feels like — as I said — the corporate WhatsApp. Not that Salesforce wants it to be compared that way or used …
Chose Slack
No, I use many. I use Google Meet, I use teams, I use many others. Again, it's the same, not many things, but if I'm repeating myself, it's all about sharing the information, how quickly it's effective, the quality is good, the huddle is fine, you can share all the, so all the …
Chose Slack
Microsoft Teams feels clunky in comparison to Slack. Slack feels more versatile and intuitive, and much more tech minded then Microsoft Teams does. I would say Microsoft Teams may have the advantage if your business is fully with Microsoft (ie the full Office suite), but other …
Chose Slack
I've dabbled with Microsoft Teams and Zoom's chat features in past roles at startups. Teams integrates well with Office but feels clunky for quick searches and daily chats. Zoom is great for video but lacks robust file sharing and app integrations. Slack wins for us with its …
Chose Slack
Teams and Slack both have Pros and Cons. We use both for communicating. Microsoft Teams is good from the prospective that you can set up Distribution Groups and Private Groups for sharing out links from One Drive and Sharepoint. The integration is built in so that all the …
Chose Slack
Slack has a more modern feel as far as ease of use.
Chose Slack
Slack holds up fairly well with the others. They all have the same basic features. Where they do differ is the execution. You can tell that for Teams and Discord, they had Slack in mind when they were designing their system. These two would be the closest to Slack, even in …
Chose Slack
The applications i have used earlier is not much user friendly, I can not do video calls in groups and tagging system is not available accross the company. Feedback and survey or process updated delivery feature makes Slack different than other companies. Slack is really time …
Chose Slack
I like Slack better than ClickUp, because I would spend 30-60 minutes a day updating my ClickUp tasks. The way ClickUp was used was very micromanaging. I billed by the hour, so I was willing to put in the time to alert the boss what tasks I was working on.

Chose Slack
Teams is better to schedule meetings with and integrates with Outlook well, but that leads to duplicate notifications for things, which is distracting and a waste of time. Messaging in Teams not great compared to Slack, and has the potential to have people outside your …
Chose Slack
Ease of use is a game-changer. Slack works so intuitively. People started collaborating automatically, and digital communities started to appear. We haven't seen that kind of engagement with other tools or workflows. It makes working together fun, and that is something that …

It's just an actual messaging soft ware to use, compard to other that can be underwhelming or just not useful when your company is growing, Slack keep unity and option for communication that caters anyone, depending on what they feel comfortable and with what type or works they …

Chose Slack
To me, there is no competition between Slack and Microsoft Teams. In my opinion, Slack crushes MS Teams in every regard and is a pleasure to use. I think MS Teams on the surface looks like it has a comparable feature set, but when you actually USE the app, there's no question: …

It's amazing as a daily driver for team communication, and document search/store. Also, if you're doing a lot of LONG meetings and have trouble remembering details, the AI summarization is amazing and convenient. It just works. I'm not saying I always do this, of course, but if I need to 'skim' instead of really digging into every detail from a meeting, the AI-generated summary is generally good enough that I can get away with it.

Slack suites well for multiple scenarios. (1) table stacks 1-1 and group conversations. (2) Level of integrations with external systems like, Confluence, Google Docs, JIRA, etc. (3) Nice integration with Claude allows lots of automation possible. (4) Allows external people (outside the company) to participate. This is great for direct customer interactions.

  • a safe direct messaging option.

Cons
  • The webinars feature has some missing functionally such as the ability for all users to use the Q&A feature (only those with a Microsoft Teams account can use it now), the ability to upload documents for attendees to easily access and download, and the ability for presenters and organizers to easily chat amongst themselves throughout the webinar.
  • The "Channels" organization hierarchy could be more clear. If you have several channels set up, it can get clunky and hard to find the specific channel you are looking for.
  • The MS Planner tool lacks functionality and organization. You cannot assign more than one person to a task and it's confusing when you try to share tasks with people - it would be nice if they were automatically added to someone's calendar.

  • 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. Since Microsoft Teams is included for free with our Office 365 subscription, and since we enjoy all the features, benefits, and functionality, there is no question that our team will continue to use the product

Slack sitll lacks in functionality. It's better than Skype for Business in many ways, but it is still another chat/message board app. It has limits in free version and paid versions. Also Windows app has errors that bother me, for example, I see number on one of my team's icons. It suggests that one of channels has unread messages; I check all channels - no unread messages, but that "1" still appears

Usability
I find that the chat function itself is quite clean, but once you incorporate the rest of the UI it becomes quite clunky. It feels as though there's too many features in one place, and that leads to it becoming convoluted and a little bit tedious to use. Due to that notifications can get missed which can lead to some tricky situations when working. I do find that it is easy to pick up though and help is readily available with a good support centre.

My rating was 7. Its intuitive interface and user-friendly features like channels, threads, and integrations make it excellent for team communication and onboarding. However, its usability is held back by the resource-intensive desktop app and cluttered feeling in large workspaces. The mobile app's performance and unreliable notifications have also been noted as weaknesses.

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.

Support Rating
The overall support provided by Microsoft for Microsoft Teams has been quite good but there is still some room for improvements. Microsoft needs to proactively work on fixing the open bugs in order to provide a seamless experience to the users. But over the service and experience provided by the Microsoft team have been quite satisfactory.

Whenever I've had to troubleshoot an issue with Slack (which, to be honest, has not happened very often), their online documentation has been easy to locate, easy to understand, and effective in resolving my issue. Slack's ever-growing popularity also means that there's a large community of practice out there that can be depended upon.

Teams and Slack both have Pros and Cons. We use both for communicating. Microsoft Teams is good from the prospective that you can set up Distribution Groups and Private Groups for sharing out links from One Drive and Sharepoint. The integration is built in so that all the Microsoft apps run natively with each other. Slack benefits from organizing different topics in channels that are all under one overarching project. These channels are easily created or destroyed depending on the coding issue at hand.
