Would it be conceited to believe I'm the best? :p
I'm not sure, truthfully. This past game, with all of Khush's hunches that went wrong can show it depends game-to-game.
From the games I've been in, personally, Sir_Stabbalot was great, along with Vudu, Spak, Khush, nickmitch, Decoyman, and you, as long as you're on the townie's side. It depends, a lot of time, on how much effort is put into the game from each player. Mop_it_up, Drew_MG, and Stratos have been pretty good, but I haven't played much from them, really. stevey's a wildcard, who just does whatever he wants, which works very well for him, but not for the group of townies.
From what I've seen and played, I'd have to say that it depends on the game as to who will be best. If there are circumstances where vudu feels safe, for instance, he'll be a top player right away, for instance, he's very good in the mafia. With Khush, often he has to find a spark to start things off, but once he gets going, he's on fire. Spak is probably the best player to look at when it comes to working on a team, he's quickly grasped the direction and tone I've taken, and identified and used an excellent secondary approach, that, when together, is nearly unbeatable. I list Decoyman particularly because of that Sonic mafia, way back when, when Decoyman did beat it, because we were sure he wouldn't have let GP get hit as a mafia player.
Really, I don't know if I can best determine who's best at the game. I will say that Khush, in my opinion, has been "easily detectable" when he's in the mafia, and that's what holds me back from saying him. I'd rather throw my hat off to Spak, because Spak's a great player, and when his own mafia doesn't reveal who he is, he's incredibly tough to figure out.
Of course, this all still depends on how much said player feels like playing, so it's still tough to say...
