Last I looked at WebRTC it fell back to TCP if it couldn't open a UDP session which means it's fairly useless as a game protocol.
Is that still the case or do the guarantee a non-blocking protocol?

The big difference comes in with packet drops. TCP, with its delivery and order guarantees, will cause huge outliers in latency. Even when those outliers are rare, they will make your game look completely janky. With good broadband, those outliers will be very, very rare, and the game will look good.
You're trying to turn a stream protocol into a message based protocol and you're going to experience an impedance mismatch if you try to use the wrong protocol for your use case.
Definitely. But the reality is that it won't bite you for the part of your audience that's on premium broadband and corporate networks. Conversely, it's going to really really suck for people in crowded apartments on WiFi and bad connections of all kinds. I know this because I'm operating an MMO server on Amazon AWS right now.
Depends what kind of game you're making.
