He was asking who's creative peak hit at the same time as their most successful point in their career. I think 50 wins that argument hands down. Snoop is a good number two. But like, with Hammer (to me) his creative peak came an album before his success peak with Let's Get It Started. Equally so, I don't count Em, because Marshal Mathers was (to me, and most) his creative peak, but he only got bigger after that.
