Please help a friend and I settle a debate regarding the Bulls.

Debate: Would the bulls have been better off signing grant hill or rip hamilton?

The debate is not meant to consider the fact that one player has been healthy this year while the other player hasn't. But since we have not seen Grant Hill in a Bulls uniform, and minimal of Rip, this is still seems to be an opinion based on the unknown. Both players are assumed to take on similar countracts (length and $).

Thank you.
