All of our meetings at Google are using GVC (aka Google Meet from gSuites), and while there are people who have reported problems (mostly in low bandwidth situations and/or using Firefox), my experience is that it is quite reliable. I've had video conferences from my Dad's Senior Center (obviously, pre-COVID-19) using a MiFi box, and there things were more reliable if I turned off my camera, but other than that, I've personally never had any problems using Google Meet from either a Linux box running ChromeOS, or a Chromebook. In fact, I've never had to worry about attending meetings remotely so much that I really can't speak to the reports of people complaining about Google Meet being unreliable.
