1. It does have calling, but it's integrated with Gmail.
2. Elaborate? The screen sharing in Meet is what Chrome provides in general and I see the same options when using other web-based tools like jitsi. Zoom has a native app which presumably allows it do other things, but given that Chrome can "share entire desktop," "share a window," and "share a tab w/audio" I haven't actually found myself wanting any other behavior. Also, I consider not needing a native app an advantage and Zoom's web-based offering is trash.
3. Agreed, although to be fair I only find myself wanting this when presenting slides and Google Slides does have them.
4. Zoom supports 1080p while Meet does 720p, but if you're using any video features then Zoom apparently drops to 720p as well?
5. No argument there.
6. I've literally never experienced what you're describing. If more than one person is presenting content then the first presenter might be displaced by the second, which might look like "minimizing the presented content." If you have manually pinned anyone that always takes precedence. No option to overlay in Google Meet is a major annoyance.
7. Google Meet's chat is ephemeral unless you are recording the Meet. I think this goes into a bucket of design decisions that can all be lumped together as "No one is using Google Meet as their only communication tool." I've never needed things like Zoom's DMs that are inside a call. When I'm trying to have side conversations with coworkers I just use our normal chat tools. Google Chat is probably only better than Microsoft Teams among the "real chat apps," but it's definitely better than Zoom's built-in messaging.
Two things that have made it so that I cannot stand every over video calling product is that Google Meet does automatic video brightness adjustment, which helps a lot when you don't have a great set up at home, and the audio noise cancelling is insanely good. It is hard to overemphasize how good it is. You can whistle and clap and play music and type on your obnoxious self-indulgent clackity keyboard and other people will only hear your voice, plucked cleanly out of the mess as if everything had been mic'd separately. It's by far Meet's best feature and so far no one else has come anywhere close.
