People, please stop bringing screenshots to your arguments. In most case, some game runs better(or worse) than what the screenshots actually show.
I've played the two games a lot lately (I'm almost done with Gears 2) and there's really no comparison to be made. The character models would be a tie to me (gears has better facial structure, killzone's bodies are more fluid), but anything else (textures, animations, effects, particles etc.), I think Killzone is vastly superior. Killzone shines when it's in motion.
You have to see this game in movement to realize how good it actually looks. There will never be a screenshot that will do justice to Killzone 2. On the other hand, those Gears of War screenshots are looking even better than the actual game. Again, I'm not saying Gears of War looks bad, I think it's probably the second best looking console game maybe tied with Uncharted and MGS (but those three games have all their strenghts and weaknesses).
