[Atariel]

Its prorbably Galadriel because she was the most beautiful (see Happy Elves). but don't you think that Aragorn must have had some Elven blood, because he was very weakly related to Elros, who was Elrond's brother, and thus the son of Elwing, who was an elf. A very loose link, but still some blood was there. after all, when he was on his deathbed in Minas Tirith, he said to Arwen (during the Lady Undomiel speach): 'Nay, lady, I am the last of the Numenoreans, and the latest King of the Elder days', bla bla bla. I should know, i read it every night before i go to sleep. and since all the Numenoreans Kings (i.e Aragorn) were descended from Elros, he must have had some elven blood.
Anyway, Galadriel was the best because she had the nicest hair, clothes and house. and she was older, and probably wiser. she had also seen the light of the two trees. But Legolas was most definitely the best looking and Finwe the coolest.
