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

Hmmm pretty hard to say. Owning KZ2 and not Halo 3 (but after I get my 360, H3 will probably be the first game I buy =) ), but played it at my friends house quite a bit. I think I'm going to have to say H3, although that's not to say KZ2's multiplayer isn't great either.
