Controllers you will be holding in you hands forever so you want one the feels great and doesn't hurt your hand after a while. Xbox has been doing well with making the controller they have been for a while. The biggger controller feels way better in the hand. Sony has been sticking with the smaller controllers since the PlayStation. But this year they went with a more bigger Xboxish controller making it feel better and easier for more playing time for your hands. Both companies put better features on their controllers. Xbox kept the same concept design but put more fine tuning on the joy-sticks and so did Sony. So if you liked the old Xbox controllers i'd stick with them but Sony has made a bid jump to there controllers.
