Only the top 3 PS3 games you listed matter, and the top 4 360 games you named. The rest are meh for both consoles.
So to compare the remaining ones:
MAG vs. L4D2/OSDT: Edge goes to MAG. It should be SOCOM quality, and 256 player online is just insane. How can there be a new Left 4 Dead less than a year after the original? Even EA waits a year with its sports franchises. ODST should be great but its just a spinoff..Its not Halo 4.
Uncharted 2 vs. Splinter Cell: Edge goes to Uncharted 2. It's a graphics powerhouse and the gameplay is just fantastic. I think its the best new IP of this gen (better than Gears of War even). Splinter Cell looks great, but the franchise is getting a bit old and the last couple games haven't been as great as the old ones.
PS3 wins for platformers and 360 wins for racing games by default because theres no competition. Unless Gran Turismo 5 makes 09 but thats doubtful.
Overall I give the win to PS3 based on the presumption that MAG should be as good as SOCOM (both made by zipper) and that Uncharted 2 is as good as the first one or better.
