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.

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.

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: …

Slack > Teams, but if a company's infrastructure is Microsoft, you have to use Teams. Slack + Zoom has been a good combo for chat + calls.

Slack is hands down a winner compared to these other tools. Simplicity and user choice win out every time. Also, add that it has a ton of great integrations, which means it is more than just a messaging app. It can allow you to organise your day, remind people in your team to …
Chose Slack
I have yet to try any of these but for my needs and our smaller team - I suggest going with the simplest tool is the right choice for us. As we expand moving to a more developed tool with deeper integrations would make sense.

It is well-suited for an organization with many team members who are scattered throughout different locations. It offers organization and clarity to projects, files, and tasks in one centralized location. It would be a bit of an overkill for a small organization where everyone is in the same location 5 days a week

Slack is great for tracking commits to new coding projects. You can take parts of code that still need to be implemented later and easily search through the history of comments if there is something that goes wrong with a code commitment. It can be difficult for people that only like Teams to adjust to a new platform if you are using both to communicate.

Cons
Microsoft
  • the calendar function can improve it's not 100% feature parody with outlook.
  • Better search for documents and contact with AI
  • offer the same security for document sharing as is available in outlook. Especially concerning PII and documents shared to "external" contacts.
  • Contact is hidden away in "Calls" and needs to be better exposed like it use too.

  • Would love a better integration with GitHub. For example, notifications when your PR is updated, when review is requested, @-mention in comments, etc.
  • Improved "Later" tab, for example the ability to create to-do lists or making the "Later" tab into a more powerful to-do list (annotate items with notes)
  • More powerful integrations, e.g. Google Calendar could render a calendar view within Slack, rather than sending the daily schedule

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

To be more transparent, I give 10 because Slack serves our collaboration needs. It provide us a good platform for team communication relaying important update within the company, it has even mobile app where you can install in your phone to monitor any updates within that team that needs your immediate attention and intervention.

Usability
Microsoft
If you have the full Microsoft Office suite, it works really well because it's integrated well within its ecosystem, but if not, it can be annoying because it tries to open a shared file in the web versions of the file equivalents. The web version is also a bit slow, and the login is very difficult to handle if you have multiple Microsoft or Outlook accounts.

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.

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.

Microsoft Teams offers a much more integrated experience between their chat and video call function compared to Google Chat and Slack. Both other tools are much better for internal communications are they have simpler UI without other features. Whereas Microsoft Teams can be used for more critical conversations, particularly between external companies, and has been very useful in sales conversations which is what we chose it for when speaking to companies that work exclusively through Microsoft.

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.
One of my jobs used Hive - I mostly just ran it in the background in case anyone messaged me. I did not use it often.

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
  • Because our unit decided to go all in with Microsoft Products, the integration and flow of our communication and files are seamless.
  • Microsoft Teams is very secure. Only those who are logged in with their university credentials can access the files we share and the events we host. Therefore, we don't have to worry about privacy and security for the virtual events we host.
  • If our virtual events are open to the public, joiners outside the organization often struggle to join because Microsoft Teams is not the most familiar tool amongst the public.
