My company tried to use Google Meet. With a group of around 16 people, Google Meet had all sorts of connection quality issues—people's voices cut out while talking, sounded garbled, etc.

A week later, we tried Zoom instead. We could hear everyone clearly. We've used Zoom ever since.

I had some say in the decision to continue with Zoom, and I feel kind of bad about choosing it, but it's hard to argue with the results. We had similar issues with Slack video calls (although we still use those for small groups—not my decision!), Microsoft Teams, and a product from LogMeIn called Join.Me. Unlike Zoom but like Google Meet, these products are all based on WebRTC, and I'm starting to conclude that WebRTC is just a crappy technology for large-group video calls.

We admittedly haven't tried Jitsi. Perhaps I'm part of the problem, but I don't want to be the one to suggest a random product no one has heard of. Especially when that product is also based on WebRTC.
