My team does weekly Google Meet meetings along with WebEx. The biggest complaint I'd have is that Meet sacrifices functionality for cleanliness; everything useful is hidden behind some menu or popover, and you can only open one popover at a time (otherwise whatever you had open closes). This contrasts widely with WebEx, where most things (participants, controls, chat) can be shown at the same time, but also hidden if you don't want to see them. Meet seems complicated in comparison because views that are 0 clicks away on WebEx require 1-2 in Meet.
Basically what other comments suggested. The popup menu that shows every time I move with the cursor and covers part of the screen. Can't be hidden on demand. Shows status I can't see without opening it (and covering part of the screen). Can't change my mute status without opening it (and covering part of the screen) or using a very obscure shortcut.
I am confused. The microphone button is on the bottom bar, is clearly available at all times, and can always be clicked-on.
You are using Google Meet within a browser?
Out of these I'm really surprised how "not as horrible" MS Teams are. Loads of functionality and the UX is bearable.
