a very close battle.
This is another battle that is more than meets the eye. After digging around Mao's profile, I figured out that Nimbus was spinning titles of Mao's previous songs, but even though it rhymed, it didn't really hit hard, and I was confused by all the Mayo remarks, when I had always assumed Mao had more to do with Mao Zedong. Nonetheless, Nimbus ran with it well.
I think the punches were heavily in Mao's favor. In his first verse alone he commented on Nimbus quoting Poe and Weird tales, dragging him across the Mason Dixon, and running to Jersey and Nimbus spent his entire second verse defending himself against what Mao said without really retaliating with punches. (For example: when Mao attacked with plagiarism Nimbus responded with "i'm shouting my inspiration"..when Mao attacked with dragging across the line the rebuttal was "not in this lifetime" which is essentially just saying "no you wont"
Just doing the math of how many times Mao attacked multiple elements of Nimbus on a personal level compared to very general attacks by Nimbus, I have to go with MickeyMao in this battle. This is another circumstance that I'd rather listen to Nimbus' record, but this is a battle, and Mao was firing them off the whole time while Nimbus was on cruise control. Nimbus' delivery and complexity were superior by a decent amount, but I don't think it was so substantial that it made up for how many punches Mao through that were unreturned. Nimbus is a better rapper. Mao had a better battle.
