User blog comment:Apester/Feitan Versus Illumi/@comment-14902757-20130927011008

I don't think there's anything wrong with comparing power levels. This is fun, right?

For me, I think Feitan is definitely much stronger. Nen users of their level have very good understanding of power levels. It appears to me that Feitan is not threatened by Hisoka's presence/power while Illumi has reservations in harming Gon because of what Hisoka might do to him. Technique wise, as a manipulator, Illumi must be really formidable. But I can't see him landing a needle on Feitan considering Feitan is the fastest Troupe member (without even trying) and as shown with his battle against Zazan, even Kalluto was surprised with his speed which means Kalluto probably expected that the troupe members are around his brother, Illumi's level. I would think that Kalluto's understanding of the Troupe's strength/powerlevels is based on the fact that Silva defeated one of them, but then warned them that the Troupe are dangerous... So if Kalluto thought that he could get to #2 position in no time because Silva killed one of them but only a bit wary of their strength, Kalluto must have thought that the strongest in the team is around his father's or brother's level, but he's clearly mistaken. In that case, it's problematic for Illumi to defeat Feitan. Sorry, I always have the tendency to overthink HxH related matters :)
