Xbox 360, I'm a huge halo fan and I also like gears and Alan wake, I'm not interested in most of the ps3 exclusives and I prefer microsofts system of having a handful of super hyped epic exclusives over sony's system of having dozens of small exclusives. I also prefer the Xbox controller, the achievement system and I want cross game chat. Microsoft also seems more likely to get big sci-fi exclusives(halo, gears, mass effect at first, destiny on 720 before ps4, new 720 exclusive is sci-fi, early fallout dlc, killzone and resistance look too boring and generic) which is my favorite game genre.

Microsoft also seems better at getting 3rd party dlc, I really like skyrim so i want that dlc a month ealry, Sony never delivers on 3rd party dlc, they only got a week for bf and nothing for saints row when they were supposed too. And everyone I know with a ps3 only has it to play cod for free and I hate cod so I want the console with the least cod players. I also think Xbox has a brighter future, Sony is in serious trouble and the vita and move are failing, the ps4 could be the same. And finally I prefer to buy from an american company.
