I should have clarified: best-in-class for what my friends and I need, which is essentially simultaneous multi-user voice chat that doesn't require installing an external program (if they have Chrome, it doesn't require installing anything at all), works on all platforms, doesn't mandate a laborious microphone calibration on first use, and has pretty decent echo cancellation. We were just looking to replace Vent/Teamspeak/Mumble, rather than e.g. looking for a replacement for Skype. It's been invaluable as a permanent place for our geographically-distributed friend group to idly loiter and connect to whenever anyone has a free moment.

"doesn't require installing an external program"

I had to install a .deb to use it in Firefox on Linux.
