Worse. I don't think anyone really has a Healing factor comparable to DP.
But in this case, DPs healing factor will be the winner. Unless we count something that SHOULD kill him as a death(i.e getting his chest caved in by a rocket will count as a "loss". Even IF DP will just wheeze for a minute and reform.)
ill go with deadpool. not just becuase i hate blade after the movies came out. deadpool is damn good with blades, fairly good with guns and had his teleporter to get him out of a jam. his healing factor would be the deciding factor though. without it blade would possibly win but with it deadpool wins.
