Anyway..yeah. Self explanatory. What is (or are) your favorite controller and why? This includes any kind of arcade stick, flight stick, steering wheel, or whathaveyou.
My favorite controller design of all time has to go to the Sega Saturn model 2 controller, which is model 1 in Japan. It's by far one of the most comfortable controllers I've ever had, and unlike most companies the D-pad is actually built well and practical for fighting games! I suppose the Playstation dpad is..okay but it still doesn't have the feel or the accuracy that I get with a Saturn controller. I've just never held a controller where they actually got the damn D-pad right other than the Saturn controller and this Logitech PS2 controller that I found. And of course, 6 buttons on the face, two triggers...perfect for just about anything that doesn't need analog control.
Oh and it looks effing cool.

note: Yeah I know I missed a few like the Dreamcast controller but more than 10 options would just be spammy.
Also I really love arcade sticks for fighting games (duh) and shooters over any control pad as well, but sometimes they're just not practical. Like for playing platformers or RPG's, which is why the Saturn controller gets my vote because of versatility.
