Voted: Erupt.
Kompz is dope and had a nice drop like Erupt had. However it seemed more of a generic/hype track as opposed to a diss track directed towards a certain person. Erupt too had this issue though i feel his was somewhat more direct in his approach of dropping a 'diss track'... though overall this did seem more like who can make the 'best track: battle' than a back and forth of diss tracks.
Props to both though, good to see this shit still going on on LB
