I agree too, cool thing about this board is that whether you bench 250, or 500, everyone is treated with respect, as long as they show respect, they get it in return.
That being said, I think this is a legitimate question. I don't know for sure, but I can throw out the following.
PowerlifterJay has the highest bench of anyone on the board that I know of. He is a 600 club member. I am not trying to slight anyone here. If someone has done more, please straighten me out. My guess is that he also has the best by formula.
Squat: my guess would be, Freak19, Irishpower, or Flapwrlifter, who has not posted in a while, but a few of us know him, and he is strong as shit.
Deadlift: I think Arioch. But Freak and Irish are very very good pullers too. By formula, we have a couple of smaller guys who have not been powerlifting very long who have already pulled 3 times bodyweight. I'd Rather Be Deadlifting, and Deceiver are some very very strong pullers.
By the way. I could beat Jay by formula on the bench . . . if only I could figure out some way to lose 50 or 60 lbs bodyweight without losing any off my bench.
Others who know more specifics, or know I am wrong about any of this, please let us know.
