Teams if you only use it for meetings is great, truly. It's easy and simple. Messages in the attached chat rooms of recurring meetings is really convenient. DMs work seamlessly and sort in between those meeting chats.

The problem is that the "teams" in teams are a cobbled mess that works like a combination of forums posts and chat rooms. If you have coworkers who really like that functionality, you're forced to interact with the garbage underbelly of the app. My opinion of Teams shifted drastically when we got a new PM (former MS employee) who started putting things there, making them hard to keep track of.
