Rezzy V1 - Delivery is rather uninspired and you have a lot of filler. If you're going to do that, at least compensate with stronger schemes/multis. Steve Irwin finisher is alright but 90% of people here are going to think of Wyze.
Breaker V1 - Steve Irwin flip is nice, delivery sounds like you're really enjoying yourself. Could hardly understand is nice, Master's flip is cheesy but not bad. I feel like the last several bars focused more heavily on rhyme schemes than content, but if I'm going to compare it with Rezzy's, at least you had stronger bars. One major point off for your mixing, it's hard on the ears and sounds overproduced.
Rezzy V2 - Needs to put more emphasis on the right syllables. Don't bring up Steve Irwin again, please. Fairly difficult to understand, Kangaroo Jack is a clever rhyme but a weak line. Major points off for lame 'you don't get any pussy' diss.
Breaker V2 - Kind of big down under is great. Rezzy disses are vicious, finisher is delivered well but overall I feel like the verse should have had one more personal punch in it that wasn't a flip, it would have made the entire verse sound more aggressive. Mixing sounds much better this time around.
Breaker wins easily with stronger relevant content and delivery.
