Iron Fist. The two are probably approximately equal in skill, right along side the likes of Wolverine, Captain America, Batman, Shiva, Shang Chi, Et Cetera.
However, Danny can chi amp to levels of strength and speed that put matt to shame. Not to even mention the fact that he packs a punch that could liquify Daredevil in a single hit.
Wolverine & Cap > Daredevil > Shang Chi = Iron Fist
Daredevil has time on time proven to be a worthy challenge to Cap.
Wolverine, who is equal with Cap, easily handed Shang Chi his ass.
And Shang Chi is equal to Iron Fist in skill.
In skill, Daredevil is a class between Cap and Iron Fist.
So he takes the skill category.
I know ABC logic don't work, but in skill, it does.
Cap isn't a better fighter. The guy only knows boxing and judo.
Wolverine has never really shown any true skill in fights. If he has no on panel feats of skill, then he doesn't have those skills. Narrators and bios don't mean anything. The only time Wolverine shows even the slightest bit of skill is when he trains. And he had a wood sword.
But, if DD gets hit by the punch, he's dead as hell.
