At least in the movie, definitly Aragorn.
To stay faithful forever, when you know in your heart she has already left for the west, thats a hard thing to do. And to be able to kick huge amounts of orc butt on the side, along with being ruggedly handsome and fit, AND to do the right thing and take the power granted you, although you know what happened to the last who did, AND to resist the ring successfully, and to be a good friend to little hobbitses, AND to chill out wiht an elf and a dwarf, well, that is something to aspire to indead.
