Well, Legolas has an advantage with his "elf eyes" (God, I hate that line), I think that if he had normal human vision Robin Hood would beat him. King Arthur would kick Aragorn's @ss, Excalibur can slice through most metals, and even though Anduril is an extra magical sword, Aragorn is a looooooong descendent of Isildur, whereas Arthur is the original and rightful king. Then too, Excalibur is a broadsword which takes greater strength to wield (Anduril is a basic longsword), and Arthur fought in far more battles than Aragorn. Frodo and Harry Potter would be a close one if Frodo could use the Ring and Harry could use his Invisibility Cloak; of course, if they're fighting in the woods Frodo would have the advantage. Now if Frodo could use the Ring and Harry could use his wand, Harry might win if he got a lucky shot. If Harry isn't allowed to use his wand, then he's screwed; Frodo would just sneak up behind him. However, if Frodo is not allowed to use the Ring and Harry is allowed to use his Cloak, Frodo would still win because Harry would make too much noise. Basically, this one could go either way. Voldemort vs. Sauron....Sauron, no doubt about it. Gandalf vs. Dumbledore....Gandalf, he's had a millenia of magical practice and learning; Dumbledore's had what, a century? Voldemort vs. Dumbledore...Dumbledore, good always beats evil; this goes for Gandalf vs. Voldemort as well; not to mention Voldemort's a wuss. Dumbledore vs. Sauron...possible for Dumbledore to inflict a mortal wound; but he would doubtless be killed in the process. Finally, Gandalf vs. Sauron...Gandalf, good over evil thing again, though he would probably be fatally wounded in the process. This outcome would be the same even if Sauron could use the Ring. How about some good ol' sibling rivalry? Boromir vs. Faramir; Elladan vs. Elrohir, Eomer vs. Eowyn and so on. (Personally, I'd have Faramir beat Boromir and Eomer beat Eowyn; mainly because I love Faramir and don't want any competition.)
