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

[Scruff7]

it all goes down to your own personal tastes.

For me, Killzone 2 has the most addictive and impressive multiplayer.

I never got into the Halo multiplayer, its good and freeflowing. it works perfectly for what it does, it just wasn't my thing.

K2 on the other hand, is exactly the sort of multiplayer i want. structured, gritty and tactical.
