Sorry, what has Drake done? Not to mention Wayne has the greatest flow that I have ever heard. The dude could literally say whatever and it would come out great. I feel like HB just has a hate on for him because he is currently (and this is not my opinion, it pretty much is a fact at this point) the most popular act in rap. It's easy to say that less popular and undoubtedly more talented people are better, but untill Drake sells one million copies in one week or comes out with like a million songs in one year without an album or at least comes out with some music that changes peoples perception of hip-hop, he is never gonna be better than Wayne.
Also, if he really ever wants to blow up, I am sure that signing under another rapper is not the best way of doing it.
