Okay then, seriously I think the PS3 is a superior system and any exclusive game that you can get on the 360 (like mass effect) usually goes to the PC anyways. However, since you both like FPS and have friends that have 360, I say buy that as long as you don't mind paying for xbox live.
The most joy you'll get from your system is playing with other friends, and you'll probably meet at least some people when you move that have an Xbox, but more importantly you can keep in touch with your old friends via playing online. So unless you don't think your going to (or want to) play with friends on Live, the xbox seems like a better choice for you.
Again, as long as you are going to be playing with friends and don't mind paying for Xbox live (which isn't unfairly priced but still, its not free...).

Seriously though, apart from that one god of a game, the 360 doesn't have much in terms of exclusivity,
nor does the PS3 for that matter of fact.
Uh, God of War, Little big Planet, FFXIII Versus, Yakuza 3&4, Twisted Metal, SOCOM, KillZone, Metal Gear Solid 4. Heck, I'd buy a PS3 just to play Uncharted 1 & 2.
