We've been using Google Meet at my work for daily "standups." Typically 4-6 people, lasting 15-30 mins. Been very smooth sailing, even using Firefox. Out of curiosity, what kind of issues were you running into?
This has been my only experience with Meet, but first impressions do tend to carry a certain weight. It's entirely possible this was an unfortunate coincidence, and that the service is typically as reliable as other solutions. My limited personal experience with Meet, and previously with Hangouts, does not support this however.
