Hmmm...
Not digging Fat Beats flow at all, or voice, or delivery... Sounds VERY mediocre.
Unfortuantely, I'm not really feeling HeavyUrb either, so this is a really difficult decision for me.
Fat Beats is too quiet in a way, I don't like the flow and the voice is quite annoying in a way. BUT, he still has my vote.
Heavy Urb's flow is quite a bit off, or maybe his voice is just way too loud over the beat, making it hard to tell. Lots of his lines seemed slurred and it sounds as if he had difficulty pronouncing them or something.
So Fat Beats has my vote this round.
