Killzone 2 > MW2

[nightsurge]

^Its called Ground War.

MW2 has such a mix of game types and game sizes that it appeals to most anyone. 18 or less is just better for MP in my opinion. I owned KZ2 for a while back in the day and it was fun, but the game was just not balanced very well and the maps weren't designed well for different game sizes. Some maps were way too big, even with 32 people, and some maps were way too small.
