sure, he's not as dope as he was before (i just listened to Reasonable Doubt today and was still blown away), but in my opinion, he's still better than almost everyone out now, though that might not be saying much.
that being said, if you're basing it on his recent stuff--as good as i think it is--he may not be that more incredible than a lot of others. however, if you look at his career as whole--as well as the influence he has had on EVERY other rapper, regardless of what they might say--I think he easily has enough to put him in the top 10, maybe 5.
