I haven't comparison shopped yet. And, for that matter, I haven't initiated any Zoom meeting myself, except once when someone else requested I do so. (I used Blackboard to meet with my classes.) I just noticed that it's been popular with others, and I've gotten it up and running with no effort.
I am trying out MS Teams, but it's a pain to setup. Multiple emails back and forth to tech support, and apparently I have to go in and manually add every person I want included. From what I can tell, it seems to be designed around a rather elaborate setup, in a situation where you consistently communicate with the same handful of people.
With Zoom, it's "click on this link". You don't have to have configured anything in advance. Especially useful when you want your meetings to be open.
As an example, you can now watch the Number Theory Seminar at MIT, live:
