I haven't used lots of videoconference tools, but Zoom has a killer feature I haven't seen elsewhere: The ability to put camera feeds on one screen and screenshare on another. If you're using a laptop's built-in webcam, and you have external monitors, that makes the "video meeting with a screenshare" experience noticeably better.
