I've been using WebEx in enterprise/corporate environment for couple of years intensively, and it "just works". I can download desktop client, but I can also just run it on browser.
Zoom always wants to install weird clients that violate policies and cause my corporate laptops to refuse or bork.
I recognize my experience may be a minority one, but I'm surprised, genuinely, at this perception that it's "the one video conferencing software" that works.
