This old Steel Serpent/Spidey fight is probably a better commentary on how Danny and Spidey stack up than any of their head to head fights, because those usually always end without a winner or have one guy holding back:
Speed and strength here. Davos, without the Iron Fist or any outside chi amping, is quick enough to catch Spidey's foot in mid leap, and strong enough lift him as if he's light as a feather and use him as a club, than throw him into a tree.
And here's the entire Steel Serpent/Spidey match, when SS has the Iron Fist:
So Spidey misses with his first two punches, gets thrown twice, and than ends up on the defensive for the rest of the fight until he's cornered.
Kind of hard to say Spidey has any advantage at all, if the best he can manage is to barely dodge what are obviously full power killing strikes, and deliver ineffective counters in return. Especially considering Spidey has Spider Sense, and Davos doesn't.
And like I said, Spidey hit him from behind, yet he's the one who got KOed.
