Graphics: Killzone 2 or Gears of War II?

[masschamber]

Gears 2, it doesn't look much better than the first perse, especially given that I'd stand by it as the best looking game on consoles, but the scoop seems so much grander,
Killzone 2 takes nextgen gray to a whole new level of looking dead, though it still looks great
....
anyone have any frame rate info about the 2 games as I find framerate very important in how a game looks I mean killzone 1 would have looked fantastic if it ran at more than about 10 frame per second
if killzone 2 runs at 60 steady it would be far more impressive than gears, but if both are 30 gears wins
