This is a real WTF moment right here. What are the others?
In terms of overall controller preference, my top 3 is something like:
Dualshock (All of them. 4 is best right now)
NES
Neo Geo pad
I also really liked the original xbox controllers, both the big one and the S.
EDIT: I also modded a nice custom fightstick with sanwa parts. That is very nice to use.
