It doesn't matter if Knuckle is an Emitter or a Conjurer. The respective combat situations of Knuckle and Kite prove Kite is superior in a Nen brawl. Kite was putting no effort against the Chimera Ants, while Knuckle was putting some effort against Gon. They were both holding back, but Kite was holding back to a larger degree. Yet Kite's complete lack of effort was enough for Gon to say he's Knuckle's physical equal.
Kite is winning in a Nen brawl even if Knuckle was an Emitter(I think he is).
