From what I've seen from both Illumi and Feitan I;d have to give the win the Feitan with relative ease. Firstly, I don't see any way Illumi can even land a hit on Feitan especially considering he was incredibly fast even when nowhere near his maximum speed and power. Even Kalluto who was used to seeing Killua (who is very fast himself in base) could not comprehend how fast Feitan was, and this was him when he was nowhere near his full speed.

Secondly, if his pain packer means the rest of the phantom troupe have to run for their lives to try and save themselves, I highly doubt Illumi has something in his Arsenal so that he can defend against it.

In short, Feitan is very underrated and could easily defeat Illumi (from what we know of his current abilities and hype)
