The first fight between Sanji and Killingham was off screen, so it's really hard to judge it when we saw nothing.
Also I don't why you are trying to heavily downplay Killingham lately. Maybe
@Shiroyru is right and you really are just salty that Killingham ranked very high over most of your favorites in the global poll.
When I said I won't fully judge Killingham power, obviously I meant Omen Killingham.
Just like with King and Queen, I still don't believe the gap between Sommers and Killingham is that huge.
If Killingham power level and portrayal truly ends up being trash or underwhelming during his fight against Sanji, then alright maybe the gap between Sommers and Killingham is huge.
As I said before I won't fully judge Killingham or more specifically Omen Killingham until I see more from him during his fight against Sanji.
