I too don't get how Zoom is considered "the superior software". Maybe the calls don't drop, but the experience is bad (at least on macOS).
It _is_ bad on macOS. It used to be one of the better platforms to stream video content to others, but now it just lacks in many areas compared to most of its competitors.
The worst bug I had was it essentially started muting random people on a call, but only for me. I could see their mouth moving, and thought it was a problem their side but turns out everyone else could hear them apart from me. I could hear everyone else too apart from them.
