I agree with Garden Blocc beating out the Crest. (on a side note, MD passed almost 4 years ago, that's insane.)
Fillmoe is up there too with Quinn, Mess, Ya Boy, JT, Big Rich, etc.
Bed-Stuy Brooklyn is worth mentioning on the strength of Biggie & Mos Def alone.
There's probly more hoods but i can't really think right now.
