Truth is, it has the best video quality I've seen out of any of the video conferencing tools out there by a mile. Only Facetime comes close and it's limited to apple hardware and has more limited screen collaboration tools.

As a result, they're going to have staying power.

Maybe I'm biased but video quality doesn't really bother me nearly as much as audio quality, and Zoom kinda sucks there. Part of it is the codec, but their AEC is so godawful we have to force everyone on calls to use headphones.

Video quality is really only necessary when screen sharing, and zoom does OK there.

I haven't heard this abbreviation before but I assume it means Audio Echoing Cancellation.

Usually Acoustic Echo Cancellation but yes. When it's good you don't notice it (several commercial audio installation products do a great job at it) but when it's bad it's really bad. I'm not sure if Zoom even bothers.

Can’t tell the difference between zoom and slack in terms of video quality. Both are perfect.
