yeah, luffy is much more determined, in the lucci fight, he got knocked down, couldn't move, got back up started fighting again, and got hit with another attack that knocked him down, and continued to destroy lucci.
Gohan vs Recoomb: He basically kept getting back up, until he got beat near to death. The spirit was willing, but the body finished. You can't do much better then that.
I don't believe either character is lacking in that department.
