What is the difference between Hulk's, Wolverine's and Deadpool's healing abilities?

Hulk draws mass from another dimension to fill his wounds and his healing is enhanced by gamma radiation. It's the fastest of any of the trio. It combats absolutely everything.

Wolverine simply generates tissue rapidly to heal. His is the slowest of the trio, blocked in part by the adamantium in his bones. His healing factor comes naturally, and is the only one to do so. It combats most everything.

Deadpool's healing factor is a mere copy of Wolverine's and, while not the fastest, is extraordinarily efficient. It combats everything except his pre-existing cancer.
