I'm in the same shoes about new job having to use teams and I wildly disagree. It is awful.

The best part of it is the noise cancellation on the microphone in calls seem pretty good and having a chat created for meetings is a good integration. BUT..

• voice quality significantly decreases as soon as it's more than 2 participants.. you can clearly tell the difference as soon as a 3rd member is invited.
• annotating on the screen share is extremely useful in slack (not sure if zoom has it too), not a thing I could find in teams
• the channels Vs chats separation in the UI is just weird
• the chats don't have threads.. that's such a strong feature to contain conversations. I know the channels kinda serve this purpose but it feels weird to use them and closer to sending an email or posting on a forum than directly talking to someone (with having to write a title and bring presented in 1-2 messages per screen due to the size

Compared to zoom, I guess it's not a big deal really. I'd prefer zoom but it's oh well. Compared to slack (which has it's own set of problems, but still) however it seems like a pile of shit in my opinion.
