I haven't personally used Google Meet, but part of what drew me to Zoom:
- General preference for non-ad supported business model.
- Google Meet wasn't an option until very recently.
- I really dislike hangouts and how it leaks chat all over Gmail (among other things), and this has biased me against their other products.
- Similarly, I was a huge fan of Google Voice which was way ahead of its time and which they abandoned for years until many other multi-billion dollar companies rose up and took the space.
- I've anecdotally heard Meet had worse video/audio quality from friends.
- I tend to try and avoid Google chat products since they're usually a mess and often killed.
Of all of these, the first and last are really the only valid reasons.
Google Meet does have its own scummy practices though (adding itself to meetings without asking which confuses participants and is extremely annoying, Benedict Evans tweeted/wrote about this).
Maybe Jitsi works well enough to actually use? I already have a Matrix server, I could try getting friends to use that instead (realistically probably will be difficult).
