I agree with this. I'd also add on that it isn't about "who's stronger than who?" It's about "who is the better user of Nen?" And Illumi's Nen abilities mostly rely on Needles and if he can't a needle on Feitan because he's, as Ben said, the fastest of the Troupe members, then his ability won't work.
