Halo 3 or Killzone 2. Which has the better Multiplayer feature?

[Rpruett]

Halo is living off the success of the original Halo as far as I'm concerned. It's well liked because it takes about 30 minutes to get a good feel for the controls. So it's easy to jump into.

I prefer KZ2 over Halo 3. But Halo is better known. KZ2 is CoD-esque....Which Halo is not.
