It's like I said before, much of it has to do with art style of the game.
Look at all thegames you listed...Riddick, Chaos Theory, Doom 3, God of War 2, Killzone 2, Uncharted 2, God of War 3, GT5....what do they all have in common?
Now look at Microsoft's output...Blue Dragon, Lost Odyssey, Fable, Banjo, Viva Pinata, Perfect Dark, Kameo, Crackdown...
Quite literally, the games Microsoft commissioned from it's first party devs and 3rd party partners have more stylized aesthetics.
The other reason is that pretty much eery single Microsoft studio has released games in a timely manner, and supported the system since launch.
How long did Killzone 2, God of War 3, and GT5 take to come on to the PS3? Sony has had a BIG issue with managing its studios and to get timely releases. Sony launched a year later with games that weren't as impressive as Gears 1 and every multiplatform game performed worse on the system, not to mentioned the embarassment from all the previous boasting over tech specs. They literally poured millions of dollars to save face with the whole Killzone CGI debacle and got hundreds of people over half a decade with an insane budget to develop Killzone 2 (which got the ball rolling on Sony's tech side). Microsoft never felt that overwhelming pressure to prove their hardware. Their teams were consistently pushing out games that looked great and 3rd party devs were leading on the system with great results.
So yeah, now we've come to a point where people will always point to a handful of first party Sony games, and this is how we got here.
If you still don't get it why there are no specific standouts for the 360 from Microsoft while there are from Sony then here's the short version: stylized aesthetics, consistent multiplatform superiority, less pressure to prove hardware.
