I wouldn't say he's that self-centered; his bio in the manga suggests he unintentionally comes off as mean, which is why people "misunderstand" him. Regardless, I think Araki nailed it pretty well with that statement. I personally enjoy Part 4 more because of the overall cast and setting, but I like Jotaro more as a character because I respect him as a hero, where as Josuke comes across more as a bro.

Though my opinion may be affected by how much I like him in Parts 4 and 6.
