Alright, let's get this started.

Anything less than a vote for Doom in this match, is a vote for madness. Isn't that right, Doctor?
Doctor Doom: That is correct, Thrawn.Now, if you'll allow me to extoll your virtues to the Fight Club voters...
Doctor Doom: YOU MAY! It was these same sniveling fools after all, who thought Wonder Woman could defeat me. Educate them properly lest they be ground into dust underneath my boot heel.Now where was I? Oh yes, Doctor Doom definitely takes Iron Man. It's not a cakewalk, but he does. Everything Crazychris said, I agree with:
I think Doom would win the majority of the time in a straight-up brawl. Doom is at least close to Tony in terms of scientific power and sours ahead of Tony in magical power. In terms of strategic thinking I think Doom has a better track record. His reign over Latveria lasted much longer than Tony's command over SHIELD, for instance. Overall Doom just has more going for him. This isn't a blowout by any means but I'm fairly secure in my vote.

Let me begin by elaborating on Doctor Doom's basic info, powers, abilities, and skills.
Doctor Doom: Yes, good. Talk slowly so the peasants can understand you and benefit fully from their impending education about all things Doom. This is going to take much longer if you keep interrupting me Doctor.
Doctor Doom is smarter than Iron Man. Tony Stark himself has admitted as much before in the comics. Scientifically, tactically, politically. Doom is just better than Iron Man. That says a lot, because we all know Tony has an ego.
Now Iron Man is a super genius too [Insert Wile E. Coyote joke here], in fact Iron Man is one of about ten people or so Doom actually does acknowledge as a legitimate threat in the Marve U, the others generally being FF (minus Johnny

), Black Panther, Doctor Strange, Thor, Hulk, Silver Surfer, Thanos, and a few others.
So Iron Man in in some very prestigious company; but despite that, Iron Man is still not as smart as Doom.
Genius-level Intellect: Doctor Doom's most dangerous weapon is his genius-level intellect. He is easily one of the top mortal minds on the planet. Doom has constructed hundreds of devices, including a working time machine (the first of its kind on Earth), devices which can imbue people with superpowers, and many types of robots.
Doom specializes in physics, robotics, cybernetics, genetics, weapons technology, biochemistry, and time travel. He also has natural talents for leadership, strategy, politics, and manipulation.
Hand to hand, Doom easily takes Stark. Doom is a master of hand to hand combat. Tony is not.
In point of fact, if Iron Man's suit gets damaged, he can no longer fight. That is not true with Doom.
The deciding factor in this matchup, the trump card, something Iron Man has no answer for, is Doctor Doom's sorcery.
Doctor Doom is a master level sorcerer. Few in the Marvel U surpass him, his obvious superior in the magical arts being Doctor Strange.
Gypsy Sorcery: Doctor Doom's potential in the mystic arts comes from the Roma (i.e. Gypsies) heritage of his mother. He learned these abilities from his time with a secret order of monks in Tibet. He further developed his abilities by traveling through time and learning lost Dark Arts.
Doctor Strange originally considered him magically proficient but only a mid-level mage, but now considers Doom one of the most powerful practitioners of sorcery and a potential Sorcerer Supreme.
That's Doctor Strange, the single most powerful sorcerer in the entire Marvel U; the guy who has beaten Shuma Gorath.
His (Doom) knowledge and power is great enough to hold his own against the likes of Morgan le Fay and Doctor Voodoo, the current Sorcerer Supreme. His knowledge of spell-craft likely surpasses Doctor Strange's, former Sorcerer Supreme.
So Doom has two ways to hit you, science and sorcery.
However, he considers his scientific abilities to be more important and has devices that do many of the same things.
Mystical Blasts
Mystical Force-fields
Invoke Entities
Spell Casting
Summoning
Teleportation
Dimensional Travel
Mystical Ensnaring
Mystical Portals
Doom can also transfer his mind into other beings, though he rarely uses it:
Mind Transference: By training with an alien race, Doom has gained the ability to switch his mind with that of another nearby human being with whom he's made eye contact, a process which he learned from the alien Ovoids. However, Doom prefers his own body and only uses this transference power as a last resort.
The sorcery trump card simply outclasses anything Iron Man brings to the table. When you combine that with science that can match Iron Man's, a greater hand to hand ability as a fighter, and the fact that Fight Club is these two guys going all out, Doctor Doom is the clear winner.
