Diamond based on aura because his name alone induces a pavlovian response in the chat with mf's salivating like dogs whenever he joins a lobby. Reputation = Aura.

And if you were to base it off of pure technical ability, he wins as well, along with strategic foresight, and self-control. Call him a runner, but at the end of the day, you're either a winner or a loser. He understands the psychological game. And that it's an equally important battle.

Diamond in his prime years > everyone else. iTemp, Felnin, Shmevin are the only one's who even come within a ballpark of that, however, Shmevin win's on style/aesthetics/ & BALLS.
