Kinda an unfair fight in my mind, but it was inspired by another one of those Russian snackfood commercial:
I can’t decide yet, but this commercial rocks. 
This poll needs an ‘ass’ option.
I gotta go with HP. Magic and whatnot.
I’m am curious of the reasons people voting for Frodo have.
I’ve gotta side with Frodo because of his sheer ability to endure the pain of magic. Consider what happens when anybody else in Middle Earth holds the ring: they get corrupted in all of about 10 seconds. Some of them get a little corrupted just looking at it (think Galadriel). He may have a ‘magic’ gene, but Harry’s still essentially a human. Frodo may not show that he has a lot power per se, but it’s there under the surface, somehow. If nothing else, he could take the magic hits Harry would deal, then get into close range with his, you know, shirt of mithril and legendary orc-slaying short sword (aka Real Weapons).
