well, i rented cod2 recently, and i hated the multiplayer, dont kno why, just dont like dieing so dam fast. Since ur all competitive, i reccommend PDZ, but i'll tell u this, even though its not repitive, its not an addicting game either, u might get bored real easily. Like me, i played for about 3 months, quit, then i played all of july, and now i stopped again.
Its also real easy to get good in the game considerigng who u'll be playing with on the forum(some of the best people in pdz are on this forum.) but you'll be at a severe disadvantage when u play, cause u've gotten dependant on auto aim.
But in all hoesty, the competitivness of pdz is dieing, top teams are hating on eachother, people are stopping to play this game, such as irken, who's mainly for cod2 now, and more.
So in all honesty, get GOW not pdz, so wait for a while b4 u pick up ur game.
as for competitivness,
www.gamebattles.com , that'll tell you enough for competition.
