This is how would try to solve the dilemma:

- Can he really make a (qualitative) difference, or ships he just faster and a little more elegant?

- If yes, hire him and let him work wherever he wants but in your office (at home, an external office, ...). Communicate via email.

- if no I would'nt hire him simply because it takes energy to digest annoying behavior. So it will have a slight negative effect on my personal performance. It will be a zero sum game.
