Honestly, the best controller is probably the wiimote + nunchuck, because it's far more ergonomic than any other of the controllers, it's wireless, and the controls are VERY intuitive. But for me, I prefer using the gamecube controller, because it's just the easiest to access everything on, and it's more comfortable for me, a scrub. also I use a claw grip for practically every other game in existence, so doing wheelies, tricking, holding items, and drifting at the same time all are quite simple for me. also it's a lot easier and more intuitive to look behind you than with wiimote + nunchuck. The closest feel for me with another controller is the classic controller/pro, but I just can't get over the swapped placement of analog stick and dpad, it just doesn't feel right.
