I'm using teams on macbook (teams have been a default communication channel of client i'm working with). It's truly terrible. Thing I hate about it the most is that it is absolutely not working well with other OS features. In example, when I do development I like to put on a 'focus' mode. Every other notification would go to the notifications bar without bothering me, but NOT TEAMS, it would stick itself out and bang my ears with a notification sound just like it would with a hammer. Once you try something great (slack) you don't want to go back.
