I was comparing how authentically cool the two are, I'm not really sure why you want to start talking about major cultural impacts. Common isn't as big as Drake, of course he can't have major cultural impact on the same scale. Then you have to consider whether the major cultural impact you speak of is even a good thing, something well clearly disagree on lol.
I'm not into current mainstream stuff (but don't confuse that with not having heard a shit load of it), I like mainstream stuff from like pre 2005, but otherwise I'm more into hip hop with a social conscious, stuff with a message. Half of what Drake does isn't even hip hop, it's basically r'n'b. Which is fine, but if I'm talking about hip hop, which I am when I'm talking about Common, then it's not even a contest between the two.
But my point was solely about how cool I think Common is, so if you agree that Drake isn't cool and Common has a modicum of cool then that's as far as the interaction really had to go haha
