Teqneek V1 - Fire hydrant line is a little cheesy. Black Moses is alright, time to disqualified twice is nice.
Prometheus V1 - Won thrice is a good flip, Carefoot line is amusing, beef line is on point, fire hydrant is a very strong flip. Bouncing on Big Red's dick, nice.
Teqneek V2 - Isn't embarrassed is lame without an explanation, you brought up Bieber yourself so don't flip it. Aliases actually aren't funny. Four fans is nice, rhyming piss with shit is good. TK and a DQ is a great line.
Prometheus V2 - Nice flow but the first bit half is all filler. Fan flip and SoundCloud are powerful. Comedy flip is good too, Lonely Island is an awesome follower. Eyedea line is lame since Teqneek sounds nothing like him. The outro was probably the worst outro I've ever heard, and I've been listening to a LOT of these battles.
Teqneek's first verse was awful, his second one was mostly barren except for two strong punches. Prometheus has stronger flips but goes ham in his second verse. I really didn't like the filler in the beginning of his second verse but he has strong delivery and his internal rhymes half-flip the 'piss and shit' line; the rhymes aren't strong, but the scheme is. Teqneek's rhymes are hit-and-miss, so honestly I don't consider that line to be quite as strong coming from him. That's not to say Prometheus' rhymes are great either - it's really shaky. Prometheus throws a couple more decent punches and then slits his own throat with his outro.
That being said, I think Prometheus still takes the battle. His flips are not only valid but also delivered better (that's why you get pissed on/Lonely Island called...) I had a lot to dislike about Prometheus in this battle as well as a lot to like, but overall I feel like that goes to show that he owned the mic and Teqneek didn't. He was memorable.
