I think the XBOX S controllers are my favorite. Everything just kinda lines up when I handle one. The white and black buttons can sometimes seem not to be placed well but usually they're used for things like changing your cammera angle and suck and you wouldn't want to accidentally hit them anyways so I guess it's a good thing.
I did once see a third party xbox controller that had white and black in a position that they should be called Z and C ala. Genesis and it sure would come in handy for playing emulated Genesis on the xbox, but alas, I have big plans for a universal adapter to use NES,SNES,Genesis and Atari 2600 controllers with so I didn't buy it.
