It works, but it burns through so much CPU your computer will be a gibbering mess. There's some pretty silly inefficiencies going on, for example; if you switch away to another window, they display a small video player while keeping the big one running the background. Each time you switch into screen sharing mode, they drag you back to the app again. If you draw on the screen, someone has screwed up their linear algebra so you end up seeing double with an extra copy of what you're drawing, in totally the wrong place.

Annoyingly it's a bit too convenient, so going out of band is a pain.

It works great for 1:1 and small group conversations, but its max meeting size (15 people I think) is an immediate disqualifier. We regularly have hundreds of people on Zoom calls with no issues.

For me Slack's video conferencing never really worked that well. Even Google Meet worked better.

YMMV, but for me ut turns my computer into a simulation of a space heater even when I'm not sharing my screen, and those gigantic unhidable toolbars makes me feel like I'm playing whack a mole more than working a times.

Oh, and yes,I "almost forgot" ! How to they even physically manage to get multiple seconds latency at times, when everyone in the call is in the same city, and where the worst connection on the call is at about 20Mbit? Are they just buffering for the heck of it, why not simply drop some frames if you get behind?

There's no video in the Android client, though (not sure about iOS). Zoom and Meet can both do that.

Yeah, I saw that. Got pretty close to pushing the button on it after this episode, and probably will soon.
