Lately, the PS3 has been getting more exclusive titles than the 360. The vast majority of releases are multiplatform. If you are looking to buy one console or the other, you will have to check out the exclusives and pick from there. Guess it would depend if you were more interested in Gears of War and Halo, or you were more into something like God of War, Uncharted, and Infamous. Whether you are willing to pay for online play, or if you are more into online FPSes would also be a factor.
