In my experience, even the somewhat disappointing performance of Jitsi is better than Hangouts. My worst case was a video call between Italy, Slovenia, Canada and 3x Korea and while Jitsi struggled, Hangouts was straight up unusable. I don't know whether Hangouts got confused and picked a geo-average server on some island or something, but Jitsi was at least mostly usable.
They have dial in phone numbers, something Google Hangouts doesn't offer for free accounts.
