Looks like another poster mentions "https://meet.jit.si". Ran a 10-second test, and it looks like it can successfully display my face. Haven't tried it for actual communication.

Not sure if they are better but at least you have FB messenger and Skype. All have desktop/web clients with video support? If anyone knows anything with more privacy focus and mobile clients please reply.

appear.in and talky.io are nice and simple video chat services using WebRTC.
