Once again, the X-men win this 10/10.
Jean can protect the entire team from the pheromones with a telekinetic shield. Or Jean and Xavier can protect the entire team telepathically like Jean did with Jessica Jones. Or they can just send Wolverine whose healing factor combined with his phenomenal willpower would protect him from Purple Man's powers. Or they could simply use any attack that is faster than the diffusion of pheromones through air plus the time it takes for them to take effect; this includes, but is not limited to, an optic blast in the face or a psi-blast in the face. Heck, even Kurt could probably teleport Killgrave's head off faster than his pheromones could take effect.
