Xbox 360 owners should i get a xbox i have ps3?

Xbox has better online service, and more people playing on it. I have both and each system has some good exclusives, I play my ps3 for single player games(uncharted, MGS4, infamous), and its cool downloading themes, music ,movies on the web browser. And I play my xbox for online games(halo 3, gears of war 2, CODWAW, left4dead), and it usually has better DLC for titles or at least gets it first(fallout 3 DLC, GTA 4 DLC, etc.).
