Guess I'll give it a whirl
Lifting Strength
Kingpin scales to breaking handcuffs. The closest force I could find is the following
So Kingpin had to apply over 2200 newtons of rapid force to break the handcuff links. I'm not to sure what that amounts to but its likely around or superior to the baseline of 545.2 kgf of Class 1
David scales to the Horde, who's able to
flip a car. According to the Internet Movie Car Database the car he flipped was a 2003 Ford Focus which has a curb weight of
2,604 lbs or 1181.155 kilograms.
So as a conclusion, David is 2.16x stronger reading strictly by the numbers, but likely the gap is smaller than that since Kingpin's feat was likely very casual while the Horde seemed like he put a great deal of effort into his showing. I'll give an edge to David but its not a big edge.
Attack Power
Kingpin scales to the following two feats
- Crushing a head which would yield 3.496e+4 Joules
- Harming Punisher and DD who scale to a 2.7333622752e+5 Joule showing
David scales to the following feats
Now I should mention, that there's some more scaling that can be done that would place David solidly above Kingpin in my view (barring a Netflix MCU revision). That being possible bullet scaling
If the bullet scaling is correct, then David is capable of harming someone mostly bullet resistant and would be able to survive assault rifle shots from 6+ shooters, and I don't think there's any real scaling that puts Kingpin above that
As a minor note for non-gun people the ammo types for the guns above come from a 12 gauge shotgun, M4s, and a Stealth Recon Scout which have the following energy values
- Shotgun: About 3203.7978 joules
- M4: 1,755 Joules
- .338 Lapua: 6,734 joules
Considering how much more concentrated the force would be I would heavily wager that David has a rather solid AP advantage here. Not enough to one shot but enough that's its a notable advantage
Durability
Kingpin upscales to his own feats
David scales from never really being damaged from any of the Horde's hits and surviving a rather massive train impact with zero damage before he trained with his abilities.
Skill
David is very not skilled. He relies mostly on choke holds, sloppy grapples and heavy punches. Kingpin, even though he's a bruiser, is a very skilled bruiser and can actually fight. This means that in a HtH engagement Kingpin will be landing more hits, be landing more solid hits and taking less damaging blows.
Final Thought
I think the following things about this (I know such good English)
- I believe David is stronger by a small but still notable amount
- I believe David hits harder than Kingpin but a moderate amount
- I believe David can take far more hits than Kingpin
- I believe Kingpin is far more skilled than David, but his style isn't something like DD or Batman that would allow him to utterly dominate a fight
Overall I think it would be long, especially with Dunn's style of choking and punches. But given his superior durability and slightly better AP I believe its a long fight he likely wins more times than he loses.
