Vader wins he is faster, he has a light saber that could hurt Doom. Vader has enough power to pull a Star Destroyer out of the sky. Vader could choke Doom while in video chat. Vader............
Did everyone forgert that doom is the most cunning character ever to exist. He drained galactus's powers so he could take the beyonders powers. He can use practically anyones advantage against them. Doom FTW
vader is powerful, but i seriously doubt he is the best choice of force user to take on doom. there are force users that are neutral that tap into both light and dark and are the most potentially powerful force users possible. and then theres pre-prequel yoda who doesnt even know how to use a lightsaber because he never needed one. lets not forget that force users have ridiculously fast reflexes not to mention the ability to kno what their opponent is going to do next.
take a look at different force user stats in the star wars roleplaying game

Mnd trick would not work on doom but vader slams him into the wall up and down.This doesn't hurt doom in the least but then vader has time to draw his saber and slice doom in half.Then agains doom has weapons and shields.Just because i'm baised to star wars i'll say vader 6/10

He's also a cumbersome, rather slow individual in the general sense. What good are "lightspeed" reflexes when his speed is garbage in comparison to other Jedi? Vader actually had to perfect a style of fighting that works around his lack of speed and uses his sheer power and Force abilities to his advantage. Even Jedi marginally weaker than him have been able to cause his trouble simply due to speed. Even non Force adepts can give Vader pause from time to time, much less a guy on the level of Dr. Doom.
Doom has so many options against Vader, it's not even funny. Conversely, there is very little Vader can do to Doom.
My argument is not that Vader would be fast to strike with the saber but rather he would be fast to defend against Doom's attack yet also be fast to use a force move from the get go.
I don't see a defense against a organ crush when the bell rings.
