Whether I'm a GM or PC, I'm always the Dice Master lol.

Back to OP though, I'm the guy that enjoys playing. If we need a GM, I'll do that. If we need a player, I'll do that. Hell I've played with 3 PCs as a player in some sessions. If I had to pick one though, I'd actually probably go player. Yeah I can do cool things as a GM, but to be able to work a build as a player just seems more legit than having a DM pet.
