Should i buy Alien vs Predator for Ps3 or 360?

I have both systems and i love both of them, now i am wondering which will be best in this game AVP. Please Help. Honestly I love the Xbox 360 controller more than the Ps3 cont. but if I were to choose, I would rather have a Ps3 than a 360. Although 360 is way more fun to play when it comes to shooting games such as COD games. I am afraid that microsoft will stop making games in the 360 in the future like what they did to the old Xbox, so I want my best games on one system. Which will it be?
