Amazing controller, an amazing user friendly interface, Killer Instinct, Crimson Dragon, Dead Rising 3, and the future Halo game(s). To me it seems like Sony is more popular with lots of people, but Microsoft has all the exclusives I want (I do not like the Killzone and Infamous series and think they are mediocre games). In the end it's all about the games, but the controller and user interface are going to be fantastic. I know it sounds stupid but I feel like of all the companies, Microsoft is the only one that offers a fine-tuned user experience for its system. Nintendo's are clunky to navigate, Sony's are fine but is just too basic.
Also I owned a PS3 since 2008 and in the first few years I had it, I loved it. Ratchet and Clank Tools of Destruction, Uncharted 1 & 2, Little Big Planet, Reistance 2, and Metal Gear Solid 4, all amazing games. Then in later years, I felt like I got nothing out of Sony's first party offerings. Infamous and Killzone were just so mediocre and boring for me (and they both got sequels). Ratchet and Clank's later PS3 offerings never were as good as the first PS3 game. Resistance 3 was a joke. I was excited for Playstation All-Stars but it ended up being absolutely terrible. The only exclusive games post 2009 that I really loved on PS3 where Little Big Planet 2, Uncharted 3, and Ni No Kuni (which I adore). I don't understand Sony's focus any more at all when it comes to software. Meanwhile the 360 during that time continued to receive Halo and Gears of War Games, along with some other unique exclusives.
