Slow, buggy, annoying interface, hogs extreme amounts of resources locally, can be used to spy on its users.

What's not to like? It's basically how Elon envisions X, an "everything app" that is actually good at nothing specific.

Agreed. It feels a bit janky here and there but otherwise works ok.

But don’t get me wrong, I wouldn’t say I like it.

I haven’t used competing apps to know, but as a forced teams user it is very sluggish, seems to break other ms apps half the time and has some strange and persistent design choices that irk me. It also crashes on its own, when I’m not using it 2-3 times a day.

It has improved in terms of features lately, but still feels very bloated and WIP most of the time. It still won’t let me control where video windows are, and I’ll never understand this.

This is our replacement for Skype, which was obviously feature deficient and getting old, but does what it’s supposed to do and doesn’t cause problems.

Not sure if there’s a good competing app in terms of video and slack functionality, integration into outlook and onedrive (both of which also annoy me and seem to be performing worse-over-time, but are unavoidable and sometimes useful.)

Now it was a few years ago I used it regularly last time, but moving to Slack was a huge relief.

One thing I remember with teams is that sending files was always a hassle. Sometimes files didn’t arrive. Files couldn’t have the same name as other previously sent files (because everything was in a onedrive folder).

Slack has much better search. It felt like I could finally find the messages I wanted to find. With teams it was a gamble.

And then there’s much better bot integration. At my work we have multiple bots that send messages when there’s e.g. production errors. We can then start thread discussions directly on that posts about the error, or link it to other channels to escalate the issue. And with a working search engine we can easily find the conversation again as a reference.

It got many small things that just adds value.
