Ummmm.....
Aren't they exactly the same character?
"A ruthless Sith warrior, second most powerful in their order. Fueled by rage, this overconfident Sith Lord wields a double sided crimson Sith Lightsaber."
The only real differences are that Maul looks cooler, and Bandon used to be a Jedi.
Anyway, I say Maul. He is a weapon and has been trained to kill since birth. He has many impressive feats in comics. Bandon just seemed like a pissed off little kid to me. While Maul was filled with hate, used it to become more powerful, but managed to keep on fighting to his maximum potential ( even though he payed dearly for his mistake in TPM), while Bandon was just bratty.
