You are not the only one. In my experience Google Meet is significantly worse than Zoom, especially under pressure. Even slight degradation in bandwidth that zoom scarcely notices causes dramatic sync and audio issues, and it almost always seems to have worse video resolution than zoom under similar network conditionns. I used to think it was only like that because I didn't have very beefy hardware but having upgraded my laptop to a very high end processor spec and lots of memory it hasn't improved at all.
I don't know where you guys work but I have worked in very big co with meeting attended by entire organization > 50 and much more. Google Meeting, in chrome, worked just fine. I am not sure about other browsers. But I prefer chrome to having to install a client. Also, I find Google Meeting interface much cleaner and easy to use than Zoom. In addition, you can record meetings; they are stored in GDrive and you can share them. Plus, you get captions and transcriptions. All in all, is a much superior product.
