I've personally never found a better alternative to Google Meet.
Plus I kind of resent Google Calendar not having reasonable plugins for other video services (Jitsi, Zoom, etc.); feels anti-trusty to me.
It just works. You get a link, you open the link, you're in.
Whenever I get a Zoom link, it first forces me to download the app. As in, you open the link and it instantly downloads an executable to my computer, which I need to then go delete. Then I need to fight the website by clicking a series of links to get to the browser version. Then I enter my name and join. Except oops, the meeting has not formally started, so it has now kicked me back to the previous page to re-enter my name. Try again, except later since if you go before it's officially started, you're doing this again.
And that's how bad Zoom is even before you start the call. The UI in Zoom calls is also worse than Google Meet. What the hell is "Join with Computer Audio"? What does that even mean?
Not perfect, yes my fans go nuts, but it works, everybody can understand how to get in, and it's rather very intuitive. I LOVE GOOGLE MEET.
Google Meet unfortunately doesn't just work as easily as it should.
Zoom does seem to do better overly severely degraded connections (and surfaces that It is happening). The experience is still pretty bad though.
It isn't native to gcal, but the zoom chrome extension works relatively well.
Meet is far from perfect (performance issues on Macs), but ease of use trumps that for me personally.
But the behavior of auto layout when someone is sharing a screen is completely weird to me. Also their new UI which rolled out to us recently is bit more complex than the simpler one before.
