(First off, just because I haven't said it yet, I'd like to make it a point that I listen/vote without reading any other reviews)
I vote Scuare on this one. I wasn't completely sold with either rapper's flow on this battle, both had some low points, but for the most part they were both good. Byron had a couple times where he sped up just to cram words in and I never like that. Both came hard with punches but Scuare had some especially good flips.
Good battle though, and props to both MCs.
