I have a free Zoom account. It's random whether or not your meeting gets a free extension past 40 minutes: you get a pop-up notice with 10 minutes left. I've had about ten calls so far with it, and maybe a third get the free extension. But...everybody knows that if the meeting dies, you can just jump back on the same link and you're in a new 40-minute meeting. Works fine for personal stuff.

Microsoft Teams is our enterprise platform, so I have no experience with the paid Zoom versions. Zoom is occasionally a little glitchy for me...I'd be hesitant to use it professionally unless the enterprise version is a LOT better. I would certainly never put clients/colleagues through the randomness of the 40-minute thing. I've occasionally had Zoom think I was in another meeting, or that some other person hosting was in another meeting. It seems a bit fickle at times.

I've long thought most of these videoconference platforms had too many little drawbacks, but I will admit I've been pleasantly surprised by Teams. Doubly surprising because I've always hated Sharepoint, and I realize that's what's running under the hood with Teams.
