I give this one to A.K.A. because he had 3 strong disses, and one was at the very beginning. He(A.K.A) had decent structure and an okay flow, but most important his rhyme was more focused( attacking.) On the other hand, though big GZ had slightly better structure, flow and good word play as well, by my observation he only had one strong diss( attack) in his whole piece, and that came at the end in the last 2 lines. He (big GZ) spent the rest of his verse just making threats. In battle u have to attack, and big GZ failed to do that enough here so that the reason for my choice.
