I've recently switched to the browser based client https://teams.microsoft.com and ditched their desktop application as I grew frustrated with its extremely slow UI. The browser client is more responsive, consumes less CPU and RAM, and uBlock some of the tracking javascript.

I can live with some of the missing features:

No noise cancellation

Audio devices are configured via windows sound settings

Can only share full screens and not individual windows

Standard Windows notification sounds and not the Teams sounds.

Maybe missing more otherwise its more or less the same app.

I've installed it as a Chrome App and it has its own window, task bar icon / shortcut and generates notifications.

I'd suggest others to try it out.
