Prometheus V1 - A couple really light punches here, and a lot of nonsense. The black Justin Bieber? Some good flow and swagging.
AxTekk V1 - Ax sounds a little wet behind the ears here. His vocals aren't the clearest, but he's pretty consistent with rebuttals and punches more consistently (pop filter and a noise gate.) The biggest issue is that his sentences get crammed together enough that it's not always clear what he's saying, or what the immediate relevance is between his punch and Prometheus.
Prometheus V2 - After Ax's verse, the slow and relaxed flow ends up posturing him quite well, and this really puts weight behind him dissing Ax's lack of clarity.
AxTekk V2 - Ax comes back hard with his flow. Not sure what changed between his first and second verses but the sheer aggression and improved clarity make this verse stand out a lot. There are some real punches here, too (Big Bang Theory.)
This is a hard battle to judge. Prometheus sounds more comfortable and consistent, whereas Ax punches harder but his first verse brought him down a lot. Prometheus rapped better, Ax battled better. I give Ax the win, but I do wish he'd come a bit stronger.
