Every year my family and I have a big group call with 10-20 participants. We used Google Meet this year, and everyone had a lot of audio problems when more than one person tried to talk at once (I've observed the same issue when using Google Meet at work). That's fine for a business environment where there's often just one presenter, but for a big group of people trying to have a spontaneous conversation it's not good.
We've used Skype before, which worked ok -- we only tried Meet because of the no-download-required feature.
What's the best video conferencing software for conversations among a big-ish group of people, instead of presentations?
