YMMV, but one of my customers has to use WebEx and it's terrible. Particularly in large calls with many people talking, it's very slow to switch video to whoever's speaking: it takes a few seconds to even realize the voice has changed, then it flips but shows a spinny loader, and by the time the video finally appears somebody else has started talking and the sequence restarts. By contrast, this is a complete non-issue for Zoom, Meet or Teams.
