These games largely make up some of the most high profile games for both consoles imob. They share a ton of games such as eternal sonata, tales of vesperia (just announced), all sports games from ea and the 2k series. Also they both have GTA4, Devil may cry 4, far cry, bioshock, oblivion, fallout3, and ninja gaiden 2 (annouced as sigma 2). So it is all opinion whether one console is better than the other. On the technical side there are some differences to consider as well.
