All I notice is that my time going from calendar to Teams call is ~30 seconds due to slow site loading and extra clicks. Calendar to Meet call is two clicks and loads instantly with sane defaults for camera/microphone settings. It's significantly better than teams or zoom in those regards.
If you're fully immersed in the Microsoft ecosystem, going from your Outlook calendar to a Teams call is a single click, and the desktop app doesn't take as long to get into the call.
I use both and shudder every time I am forced to use the lame web app alternatives to Word, Excel & PowerPoint on desktop - mostly because my child's school runs on web alternatives. Ironically even on Android, Outlook seems to be the only major client that actually provides a unified inbox across mail accounts due to which I switched & use my Gmail accounts through it.
Having used both in a professional capacity I have to say Teams is shockingly worse than Google Meet.
I’ve never had my laptop’s sound like an Apache helicopter while on a call with Google Meet yet simply having Teams open had me searching for a bomb shelter.
