Hmm I feel like this might be an easy choice because with Lucifer mark of cain you don't become corrupt. With supernatural mark of cain it corrupts you to your very soul then you become a knight of hell once you die in your human form then you revive with your body and walk around doing what knights of hell do absolutely whatever they want.

Neither

Lucifer I would love to have spn one cause of the cool powers. But I lack in the ability of demons to feel emotions and stuff so.
