SNES standardized 4 face buttons and shoulder buttons.
Wavebird was ahead of it's time, via fantastic wireless with little lag.
Best overall, S2 Pro. First controller that is in competition with the xbox controller for my favorite in gaming. Feels great, love the buttons/layout and the mappable buttons on the back were great for Prime 4 (used them to pull up the map). I am very impressed with the S2 Pro controller.
