Does Killzone 2 take Call of Duty 4’s Crown?

[snyperdud]

I never cared too much for the COD games(I liked them,just not obsessed).

Killzone I like,but again not insane for.The online is great,but I would like more variety in the mission objectives.

Overall,I feel Halo 2 is my favorite online shooter of all time,or maybe R6:Black Arrow.
