I guess it all depends on perspective and play-style - which is why the contest doesn't have any criteria for "best hero" in the first place. I normally play 2-4 players, so typically at least 1 person includes a bunch of spirit for questing and someone else uses Tactics for combat. In those scenarios, while Aragorn is never a bad option, he's somewhat unnecessary, and I find you are typically better off running an elf and gaining access to the best weapon suite available.
