PC. obviously because it has more buttons, wasd, and a mouse. second would be PS3, because it was originally built for playstation and its a little less complicated than Xbox 360, it also has R2 besides clear and black. third would be Xbox 360, because the controller is sortof bulky and stuff and the buttons are a little confusing. but still, these are the best three controllers ever so its top 3 out of all.
it would suck to have a game on Xbox(the old one) the controller sucked.
EDIT!!!!!!: wow i just realized we were talking about SA and not IV
here we go. PC, PS2, XBOX, because the xbox controller sucks majorly.
