Nimbus - Wouldn't have gotten the song references if I hadn't seen the quotes in the lyrics. Wasted a lot of bars talking about semen, it's a major minus. Second verse has the flips but they don't sting. Overall his verses seem more like a research paper than a battle.
Mao - The clitoris line is a real eye-roller, the advantage you have over Nimbus is that you didn't stay on that topic for as long as he did. "Copyright infringement" was good but I feel like I could have made it a little meaner. Crucifixion and clergy lines were boring, I might have tried to tear up the semen lines (your bars are sterile, mine are fresh, etc etc) Second verse is similar with some alright personals and a little bit of filler.
I really wasn't feeling any strong hits either way. That being said, I feel like MadFlex had a point that Nimbus just wasn't aggressive enough. Mao wasn't exactly going ham either, but he was a bit more direct and to-the-point, even though his flow suffered a little bit. Neither came with very strong rhymes or any multies, which is a gigantic minus for both of you. Mao for the win but I think both of you were lazy as hell.
