Is there a better multiplayer game at the moment?

CoD4 > Halo 3

People annoy me.  Just because I have a high gamerscore compared to them, they immediately say, "You have no life."  I love how people know absolutely everything about you, just because they see you on the internet.  I go to school and i have a job.  Bite Me.  Another thing they say is "i bet they play all the sports games, the achievements are so easy."  That may be slightly true, but i can't help it if i like sports. (i'm a rabid hockey fan)
Also, if you were to look at other peoples gamescores on the leaderboards, mine is a third of it. (if you compare it to StripClubDJ)  So before you're about to say, "you have no life," cry me a river and drown in it.

Finally a game has pulled me away from Halo 2.  I've been playing GoW almost daily since it's release, thus giving no time for Halo.  So i've pretty much retired from Halo, unless the old clanmates wanna catch up (even though i play GoW with them).
