First and foremost as a producer, I love the beat choice. Sirch is a legend. [KOA!]
On to the battle though.
Mao's 1st verse was wack. I didn't really dig the vocal change-ups or whatever he did; it doesn't mesh very well with the rest of the track. His rhymes were also sort of off-beat for the majority of the track. He had some dope lines (the one concerning crack was dope) and his second verse was better than his first, but all in all he gets the butt-end of the stick.
Wolfie gets my vote for this.
