++Boromir
Beren's too "perfect" and personality-lacking, and like
skip has nicely elaborated, even stupid. (Besides he copies Maedhros's style by getting his hand cut off... Grr...
)
Boromir, on the other hand, is one of my favourites. I love his faults. It's so refreshing to have one not-so-perfect hero in the Fellowship.
Agan has already nominated most of his good qualities, so I won't babble about that, but I will just add that his death is one of the most beautiful in Tolkien's work.
