I have to imagine there are quite a few young'uns in this thread. If the Dual Shock 3/4 are the worst controllers you've used, you definitely have some history to visit. While the DS 2/3 was a pain for certain types of games (FPS's especially) it was great for others (ie SSX and Tony Hawk). Granted, I dislike the cheap feeling of the controllers but they're nowhere in the league of the majority of stuff listed here.
Also, the DS 4 might be tied with the Xbox 360 controller for my favorite of all time.
