It's hard to pin it down to just one. In the last year, we spent the majority of our time playing True20, but that's because we had a True Darwin's World game going, and we went from that straight into beta testing Reign of Discordia. Once RoD was out, we started up a Pathfinder beta game (which we're quite happy with), but I'm also playing C&C during some of the off weeks along with one of my usual players and my seven year old daughter. So if I had to choose, it would probably be True20, but my preferred D&D replacement game is Pathfinder.
