User blog comment:Apester/Feitan Versus Illumi/@comment-4828844-20130927113651

Since everyone has summed my opinions already, I think Feitan is stronger but I'm not saying Illumi is weak. He scares the living daylights out of Killua and he earned Hisoka's respect, a feat that doesn't occur often. I am just basing things on how much I've seen; Illumi seems to be more on the assassin side rather than real fighting like Feitan is.
