Lyrically, I think Nimbus has the edge given the beat - it sounded better, and just felt like it needed to fit. When he responded to Pig's second, it felt like he was conversing and rapping at the same time - seamless.
Pig, I know a lot of people are dissing the dick sucking comment, whatevs. It was the shock factor that really got me thinking, "oh shit, this might be a close one". It wasn't a runaway win for Nimbus, I think your own pretty well.
Overall though, Nimbus just had the delivery and the consistency to take this one hands down.
