The Dualshock is great, but I hate the location of the analog stick. It should swap places with the D-pad.
I love the Xbox controller with the exception of the awful D-pad. D-pads might not be used quite as much nowadays, but as a retro gamer at heart I just can't get behind a controller that screws over the D-pad.
The Wiimote --- uh, no. Just no.
The best controller ever is the Genesis 6-button controller. That thing was perfect.
