How the hell should we know? All we have is some quotes on him about him being a great learner and already a brilliant lightsaber duellist. Bandon as a knight was weaker then Malak thats for sure, but he exelled when he joined the Sith soon proving himself to be a great fighter with an excellent control over the force.
Bandon probably takes this, from the limited things we know he has more experience more dark side training and he has killed far more opponents. Although Malak would probably still be a real challenge to him.

Is that why you said Jedi Knight before? Because I thought if you said Jedi Knight you would mean him being as a Sith Lord. ( For those who can't tell, that's sarcasm)
Well he could have been a Jedi Knight for some time in the Mandelorian wars if you want to get specific, we don't know when he was really kicked out of the order or dropped his title 😛
