I'm genuinely surprised that no one (such as Darth) mentioned the key difference between in-world and out-of-world classification. Sure, in real life we know that Spider-Man won't die. He's an icon and a money-maker, and people would go nuts if he did.
IN-world, it's possible he'll die at any turn. Do you see any thought bubbles from Petey saying "Well, I'm gonna go challenge Galactus by myself, because it's obvious Joe Q isn't going to approve my death." No, you don't.
However, the slapstick factor of Wolverine is IN-world. IN-CHARACTER, why would he have any fear? You could seriously see a bubble saying "Well, I can't die, so what is there to lose?" In fact, you almost see that in the issue with Nitro, where he mutters about how painful it's going to be to be blown up.
At this point, Wolverine is almost a parody of himself.
And you know what the major issue here is? People (I'm talking to you, Horrorfan) are tryin to quantify fighting ability and mutant power. This is ridiculous, and it's a constant failing in comic fans.
You can't quantify a healing factor versus the ability to turn into living fire. You can't quantify super strength versus invisibility. In any given situation, one can be more valuable than the other.
There are obvious situations where quantifying can work: if you have an arm-wrestling contest between Thing and Kitty Pride, the result is simple. However, this whole "No Wolverine's fighting ability is much more evolved than Daredevil's" is bull****. They are trained in completely different styles of fighting, and the results of a combat do not have to be identical every time.
