Black Thief had a nice flow and decent rhyme scheme -- nothing too complex, but it all worked. More importantly, he brought some good wordplay and interesting references to the verse. The one time he indulged in a pussy line, it was at least above average for that kinda thing. And he stayed focused on the punchlines instead of talking himself up. Pretty solid overall.

Killa's verse wasn't terrible, but it was mostly filler. The strongest aspect of it was that he made a couple of personal disses -- which were pretty good -- but I don't think it was enough to raise the whole verse above the level of Black Thief's.

Vote goes to Black Thief.
