Good post and I pretty much agree with everything you said.
However, MAN getting hit 20 different times by a truck and getting kicked 20 different times by CHILD, I give the truck an overwhelming majority.

If Spider-Man’s skin and bones are durable enough to not take damage when lifting 20,000 pounds over his head, you would think punching him would be a lot different than punching a normal dude. Having said that, of course a street-level guy could knock Spidey out…it would just be harder than knocking out an average Street.

In relation to the original post, the question is more like who jobs more—MAN 1 to CHILD and others like him or MAN 2 to CHILD and others like him?
In other words, the majority of the time, for all intents and purposes, MAN 1 & 2 should be able to beat CHILDREN fairly easy, but which MAN loses the most to CHILDREN?

In my opinion, Spider-Man is more powerful than Wolverine.
When Spidey loses to Captain America, Batman, etc., it seems more implausible than when Wolverine loses to Captain America, Batman, etc.
