The PS3 controller is the sublime standard for controller design for me. The only thing I take issue with is the R2 and L2 triggers. I added these trigger extenders and it fixes it right up. I can't stand the face buttons on the X-box controllers. What other people call "solid" feeling, I call stiff. It's also got the single worst first party D-pad I've ever encountered.

I'm pretty intrigued by this new Mad Catz controller though. I'm heavily debating giving it a shot.
