This doesn't work perfectly well if you are on multiple calls at the same time.

Desktop Teams allows you to join multiple calls at once, and switch between them is easy.

Web browser teams disconnects you from one meeting to join another. The only solution is to open multiple browser profiles, each for different call, and then manage the 'mute tab' manually. Additionally, web browser edition has something to detect if tab is active, and will downscale / delay video stream if tab is not active. This is extremely annoying when you have meeting active on one monitor, and want to double check what is being discussed on another.

Saying all this, web browser teams at least works. Desktop one stops working because as the whole discussion here points out, accounts get mixed up. I can't join team meetings anonymously because desktop edition thinks I have an account, but when I try to login it tells me my account doesn't have Teams enabled.
