Hmmm. The story I keep hearing is companies switching from Slack to Teams, not because Teams is better, but because it's more or less integrated into O365 and has various compliance certs already. 7.1B seems a bit high when competing with MS.
Coming from a Linux background, I had lost touch with the Microsoft ecosystem for the most part of a decade and would actively avoid Microsoft related stuff.
When I got a new job, I had to use the whole SharePoint/O365/Teams stack, instead of Slack, in medium-sized teams. It feels much more lightweight and responsive, chat history and search works way better than Slack (for now, at least), and is miles ahead of Skype in terms of not dropping messages, and you know, actually allowing you to chat and call.
I'm not using the O365 integration extensively, and generally view/edit documents as they're supposed to (files), but in the cases I've needed to make some changes in an Excel file, I didn't have any issues.
Of course it suffers from all the problems that an ephemeral, short-term memory chat application does in an organization, but that's to be expected.
Edit : Not affiliated with MS in any way. If I can answer any questions, let me know.

They can also be very slow getting around to fixing things even if they are very important. They only just recently fixed so status works and notifications stopped working for more than a week without getting fixed (patched this week).
Simply integrating with 365 isn’t enough to justify its use for anyone who knows any better.
1. Click the icon to open it. Flip to another app. Multiple times during startup it will steal focus as I'm trying to do other things.
2. Flip back to another app during #1? It'll sit at "Loading Teams..." for. F'ing. ever. You won't get any notifications during this phase. You will not show up as online.
3. When it does load, I'm always 2 months back in chat conversation and have to spend 2 minutes scrolling down to the current time to see if there's anything new.
4. There is no way to skip to latest...
5. Notifications don't integrate with anything, they are custom. They are quirky and peculiar. There have been times that _none of them_ come through - no badge, no notification, no mobile push notification, no nothing - if I hadn't flipped to the app I would have no idea I got any messages at all. And yes, these are direct messages that I have notifications turned on for.
6. Uploading files is annoying as F. Drag and drop into the message. I have to click into the message input box to even start adding any other text (seems like an obvious transition to me)... when it finishes uploading you might get kicked back out of the text box because it wants to ask if this is the same file as you uploaded before.
7. When focusing on the app I'm never, read _never_, placed into the input box, even if I just saw a notification (miraculously!) that I'm trying to reply to. (Skype also has this same problem.)
8. Defaults to emailing you _for every F'ing thing under the sun_. It's an F'ing chat app, why are "you're missing the conversation!" emails the default?
9. Navigation is a clusterF. Three layers of vertical panes of navigation (ala Slack). Then add on top of that horizontal navigation _in every single one_. And not just a fixed number of tabs as navigation, you never have any idea what it's going to look like because...
10. "Integrations" is just BS. All they mean in Teams is a new tab you can add to the horizontal navigation in #9.
11. Any of their logic regarding recent conversations, recent groups, etc. and what should be displayed in the left navigation is crap. I've only got one team that I use, but I have to expand that single team to get the other "chats" in it? You've got thousands of pixels of vertical real estate here, why do I have to constantly expand the _one thing_ in the list?
12. The "wiki" has no navigation by default, you have to try and figure out (amongst the 15 different layers of navigation) where to expand to find the pages in it. Hardly a wiki, and even the editing tools are quirky and annoying - things disappear and reappear at random.
And that's just off the top of my head. This is seriously the _worst_ chat app I have ever used in my life. Some random team at MS took Skype and decided to take the worst UX features of it and make a Slack clone. The fact that they started pushing this to businesses as part of 365 should involve mass firings.
Edit: Formatting and a word... and a number.
But compliance may be. For example, Slack charges a lot of money and requires a lot of users for actual HIPAA compliance (as in signing a BAA, everything else is marketing fluff). Teams, from what I can tell, comes with a BAA out of the box.
It's hard to deny Teams when it's already bundled with 365 that we're spending $25/user/month on, but if anyone has ever used both it becomes _immediately_ obvious that it's worth the money. That's the whole approach MS is going for, and something that's very very hard for Slack to combat.
The $12/user version does NOT include a signed BAA which means it is not HIPAA compliant for all intents and purposes. Like I said, anything without a BAA that says it's HIPAA is useless marketing fluff designed to confuse people. Only the Enterprise Grid product is eligible for a BAA and I believe even then there's some large minimum contract fee.
Teams is unique in how it "ticks all the boxes" but has enough small flaws and unfinished implementations that it makes for a really, really awful tool. There are fundamental problems with the software. To name a few:
- The notifications are wildly inconsistent - sometimes I'll get 5-6 email notifications for a single message that I already saw, sometimes I'll get email + app notifications for messages I am currently viewing, sometimes I'll get no notifications via email or app, for stuff that happened when I was offline. - The way every message is like a new "post" and there can be replies - this is a unique idea, but just really bad to use in practice. When people reply to a post, it gets bumped to the bottom, so posts end up out of order. Also, all the replies to the post automatically get collapsed, making it really annoying to find anything. - The mac app decided to stop displaying new messages (for WEEKS) in certain channels including our service errors channel - I finally gave up and can only use it on the web. - the O365 file integration regularly crashes the browser and mac app. We share a lot of spreadsheets and this just sucks. Sharepoint sync on the mac breaks all the time. It spins and fails to track updates. - O365 collaboration in the browser is brittle, especially disappointing compared to where Google Docs was 5+ year ago. - The Teams search cannot find documents by name. - The messages seem to be backed by email files in sharepoint, which makes a mess in sharepoint (not that it isn't kinda a mess already).
After using the google suite at many companies for many years, and having the standard on-prem microsoft stuff, I have to say Teams is not a viable solution for a software team. Teams "ticks all the boxes" but the execution can't compare to Slack.
Remember MS tried to push Yammer to businesses as well, so not everything they do works out.
