I bought a PS3 last summer, one of the best purchases I could have ever made. Since getting it, my Xbox 360 has not seen much playing time at all. I got an Assassin's Creed 3 PS3 bundle, so that I could get a 500GB PS3 (plus getting one-month PS+ and a game with it never hurts).
My PS3 game collection is: Tales of Xillia, Tales of Symphonia Chronicles, Tales of Graces f, Final Fantasy X/X-2 HD, Kingdom Hearts 1.5 HD ReMix, Demon's Souls, Dark Souls, Dark Souls II, Star Ocean: The Last Hope International, and Ni No Kuni.
I also have Dragon's Dogma: Dark Arisen, Spelunky, Bioshock Infinite, Tomb Raider, Borderlands 2, Shadow of the Colossus, Final Fantasy VIII, Final Fantasy IX, Chrono Cross, Legend of Dragoon, Legend of Mana and Spyro 1-3 as digital games.
