errm well anyhoo back to the topic, i think being darth vader in both ways as anakin as the dark jedi human right when Windu gets killed because of what he did, and Darth Vader on lifesupport, as we know him is somewhat mutual, or there's two sides to look at it....when anakin had his limbs chopped off and his skin scorched, he was given mechanical limbs, thus giving him abnormal strength, and his crippled body was placed in a suit of armor that covered him from heat to toe....now this vader, the stereotypical one we've known for years, would be at an advantage in our world, the real world with guns (that have bullets, and not slow moving laser projectiles) because the rounds would just bounce off him, but i think other than that, in the star wars movies, yes human darth vader is more at an advatnge because he has all of his agility and top potential with his lightsaber fighting skills where he can also deflect multiple laser projections being fired at him at once, but mechanical vader has more physical strength, and his armor would most likely protect him from lasers: i mean cuz c'mon, he stopped han solo from blasting him with his hand, so what does that tell u...?
