I have to agree. I deal with vendors a lot, so I've used a bunch of different ones: GoToMeeting, BlueJeans, WebEx, Skype. And the experience of using those ones is painful. Zoom is a joy to use. Its not perfect, and I have my complaints (when I'm sharing a screen why can't I make the gallery view large so I can see everybody on a second screen??) but it has been rock solid.
