I have played a lot more online than live, and I have to say I'm better at playing online. I don't think it's a matter of pokerface for me, it's a matter of leveraging different techniques. There are some advantages to playing live, though. For one thing, it's easier to tell which of my opponents are drunk, and therefore more likely to make bad bets.
I played a little ring game of 5 card draw with some friends at a bachelor party many years ago. I was the only one not drinking, and I cleaned up.
