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.

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 …

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 …

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 …

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. …

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.

Microsoft Teams is slightly more user friendly, due to it being connected to email. It connects to your calendar and is helpful to keep everything together. The notifications are a bit more helpful on Miro because it is live. I enjoy the ease of communication on Teams. It's …

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.

If you population likes technology, then I would recommend Slack. It is more difficult to implement if not everyone is on Slack or knows how to use it. Slack was used well by some employees who loved it. Slack allowed them to plan annual events and get feedback and ideas from those involved in the event

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.

  • Huddles Run smoothly without any interferences.
  • Smooth individual calls quick and easy without any interruptions.
  • seamless notifications across multiple devices
  • The ability to easily tag a team member to urgently attend to a specific escalation.
  • Slack being user friendly and able to integrate easily with other platforms and apps.
  • How to easily open up different channels for different escalations and needs.
  • a safe direct messaging option.

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.

  • 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.

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 one of the easiest platforms to use! It is very aesthetically pleasing and you can arrange the chats and other features the way you personally like it. They kept it pretty simple for people who aren’t looking to do anything more than streamlining communication, but they definitely have options for folks to build out the Workspace more.

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.

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.

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.

Having had a lot of experience with Google Chat and Teams, Slack is far and away the better option. In comparison to Teams, Slack is much cleaner with a far more user friendly AI, Teams is far too clunky and feels tiresome to use, whereas it is super easy to pick up Slack and be able to configure it do exactly what you need. Whilst I don't find a massive difference between the usability and UI of Google Chat to Slack. Slack's range of features far outweighs Google Chat. The ease of external connections, workflows, file sharing, external connections for notifications (Make, Zapier etc), plus the huge range of apps you can connect to enhance your workspace is incredible. Google Chat does benefit from directly integrating into your Google Suite so you can get access to automatic status updates based on calendar activity, which would be nice for Slack to have

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.
