The Marvel Knights Spider-Man design of Vulture is quite cool.
But considerating how the original costume is green i like more the classic costume of Vulture.And consider that a costume that works better in the contexto of the Marvel Knights:Spider-Man storyline.
Vulture with the helmet is not the best design,i think the way several artist´s kept the Vulture design great without changes is why i prefer the original design.
I did liked the Red Vulture design but thats another character so i did not mind the design being quite diferent.
