As an expert in the field of comic book lore, particularly focusing on the Marvel Universe, I can provide an analysis of the healing factors of two of its most famous characters: Deadpool and Wolverine.

Wolverine, whose real name is Logan, possesses a regenerative healing factor that allows him to recover from virtually any wound, disease, or toxin at an accelerated rate. This healing factor also slows his aging process, making him functionally immortal. Wolverine's healing ability is tied to his mutant genes and is powered by the presence of the fictional metal adamantium, which was bonded to his skeleton.

Deadpool, on the other hand, whose real name is Wade Wilson, has a healing factor that is arguably even more potent than Wolverine's. Deadpool's healing ability is the result of the unstable experimentation with the same Weapon X program that created Wolverine's adamantium skeleton, but with a twist. Deadpool was subjected to the same process but with a different cocktail of chemicals and treatments that not only bonded adamantium to his cells but also gave him a healing factor that is even more powerful and less controlled. This healing factor allows Deadpool to regenerate damaged or destroyed areas of his body with incredible speed, and it also keeps him in a state of perpetual youth.

Comparing the two, **Deadpool's healing factor is generally considered to be superior** to Wolverine's due to its seemingly limitless capacity and lack of the pain and mental strain that Wolverine sometimes experiences. However, it's important to note that Deadpool's healing factor can also be a double-edged sword, as it sometimes prevents him from dying even when he might want to, and it can lead to unstable and unpredictable behavior due to the experimental nature of its origin.

And to complete my reply, you can't kill Logan by cutting his head except with the Muramasa blade, but Deadpool = Wolverine to me. ;) As I choose to look at it, since Deadpool's healing factor was derived from Wolverine's, then if DP's healing factor is better, it means that, in essence, Wolverine's is too.read more >>
