Halo 3, for replayability.
And the Forge!
And the Mythic Map Pack!
2 years on the market and still the number 1 FPS played on the planet.
I own both (Killzone2, Halo3), and if you're like me, you'll have more fun with Halo than with Killzone.
Killzone is awesome, don't get me wrong, but the awesomness and the fun factor didn't last long for me. Too generic maybe?
