I'd say Plan B.
Rap album to soul album to hip hop album, writes and produces his own material, wrote and directed his own movie, completed the soundtrack to that movie, tackles issues that he knows won't be commercial (such as the 'Ill Manors' song) plus on top of that he tours the UK and works closely doing projects with schools and kids from poverty ridden backgrounds. Isn't bad live either, plus is a nice guy.
Labrinth is a pretty fantastic producer as well.
