Well, I have some trouble getting into Joe. He's got all the pieces: great lyrics, solid flow, good delivery, and amazing freestyling. But I just don't like the way some of his songs are organized. You know, he'll have like a 7 minute song where he just raps on and on with no chorus or break or something of that sort. I think it's a result of him having a freestyling background, so he's used to no stopping. But it can become a bit tedious when it's on a record. So that's probably why cheeseburger thinks he's monotonous. Me, I think he's great at rapping, but I just don't like the way many of his songs are organized, and I often don't like the production either.
So, I would call him a great rapper, but my favorite? No. And it's really just due to a difference in our stylistic preferences.
