We switched from google hangouts to zoom a while ago because the quality "felt" better. We are a small distributed team where our internet connections run the range of fast to slow. We didn't track numbers or anything, but fewer dropouts, frozen videos, better sound quality, etc. Maybe we all just had better internet days each time we used zoom though. Never know.

The UI is initially confusing, but so is the UI for every video chat app I've used. It seems to be the fad to have "clever" UI in video chats apps (controls that auto-hide, non-standard icons, low contrast, non standard control placement (use the standard toolbar luke!) etc.

On top of that zoom has always "just worked". The "just worked" thing is now resulting in security woes, but still. Start a meeting, send link. Done. Online works, dial in works.

Contrast with hangouts (dropped non-chrome browser support for at least a year). To this day we have users that can't use slack video for unknown reasons (app store slack doesn't work as well as slack installer slack or something). WebEx is some horror show that seems to constantly re-install itself for each meeting. You're lucky if you can get it going before the meeting is over.

Where most apps stop at video chat and maybe poor quality screen sharing, zoom has a pretty deep enterprise feature set. Good webinar support, integration with SIP systems, SSO, recording etc.
