While I do believe bias plays a role in many competitons. I'd agree with Ethereal, that this battle was close there is no clear winner. We can not say Vincent will win purely on that popularity. His lyrics showed great word play and punchlines. Etheral's lyrics also presented a complex style and knowledge of utilizing vocabulary.
I would say a tie as well, No need to express dislike upon anyone. This battle had a great match up and two very talented artists. Good luck.
