And also depends on what game u want to play.

I think xbox 360 have all the variation of exclusive game that you can choose to play.From japan rpgs such as Infinite UnDiscovery, Lost Odissey,Last Remnant to action shooting game like Gears of War, Halo, Splinter Cell and more.

If you want to play MGS4 then you have to choose PS3.But fyi, MGS Rising and FF13 is coming to 360 also.

Try study the exclusive title from both console.Which exclusive title would you prefer.Like I said previously.If PS3 have MGS4, God Of Wars and Uncharted,Xbox 360 also got its own killer exclusive title e.g. Gears Of Wars(which I recommended hardly), Halo and Splinter Cell.Don't trust the jap title for exclusivity on 360 because they only produce it on 360 as a test ground to see whether the sales are high or not.If sales are high they will ported it to PS3 with more additional content e.g Tales Of Vesperia, Eternal Sonata and Agarest War.Except for Square Enix games since their soul already blind with M$ funds.
