Just today we tried slack for video and screen share (I can only view in chrome on Linux, but that was enough for today). Slack was stable, clear, didn't drop and didn't heat up computers like Hangouts. Our two failed attempts on hangouts were right before trying slack.
We have on our list to request early access to Hangout Meet (if that is the right name).
We have a remote team, all with average home connections. The ironic part is when we try to have a meeting with the office and their network is the issue and all of us at home are still on the call and seeing clearly seeing each other.
Our experience with a Google Meet (formerly Hangouts) is that it is almost always good but during any given 30 minute meeting the audio will drop out for one person at least once. It breaks up the flow for sure but isn't a deal breaker.
