Raid, Standoff, Slums, Mirage, Grind are my favorites. Yemen and plaza are fun for HQ/Hardpoint and ground wars. NT and Hijacked are nice for racking up a lot of kills. Express is fun for sticks and stones.
I dislike Carrier, Aftermath and Turbine.
Currently Playing: Black Ops 2 Best CoDs: BLOPS2, CoD4! Love them!!!!
