My vote goes to Sangram and Andy for winning...
Sangram; I think he doesn't get involved in any crap (from the start) and has recently begun TRYING to cool people down in fights (somewhat.)... Yes, he isn't as entertaining, but I still like the dude.
Andy; because he is entertaining and still the least melodramatic (or 'game' player.. just trying to have everyone laughing, and friendly towards him.. also helps with nominations when everyone kinda likes you and has fights with everyone else.)
and maybe Kamiya- because she is really playing the game (it seems). A very smart (I think) player. It's still a fair game, but it's still a game..
