it depends on the dynamics of the game...fps are best on PC and games like Street Fighter, God of war and even FF are better on consoles...i know, you can by a joystick to use on your pc, but there is not every good game from console to the pc...
but the best difference is: the industry of games on the PCs make games that make your machine go old too fast...you have always to buy a more faster processor, more memory, more hd, more video cards....At least on the consoles, the try to take the best the machine has to offer... The games on a console life end a lot BETTER than the graphics when the console its still new...
I always played on PC but since i got my playstation my PC its just a gigantic mp3 player
