Xbox is manufactured by Microsoft and Playstation is made from sony. Xbox has XBLA which a paid service to play multiplayer games,while PSN is a free service which can be improved to premium. It really is your opinion, however, as to which games you want. My experience is that Sony has more exclusives yet more prone to crashing while the Xbox seems to be more stable as it has never crashed. The Xbox controller is more stable and the Playstation controller is lighter yet feels flimsy.
