It's quite hard to judge who would be the best isn't it, given that they all fought and fell to different people.

I think i'd probably back Húrin, Fingolfin, Ecthelion, Turgon (in his younger days) or maybe Tuor.

I think the Dwarves are underrated as far as brawling goes, there a couple that seem to be pretty clued up for battle. "Greatest" here means the most capable of destroying their opponant. It's tricky... i never thought of Ents, lol i would imagine Treebeard would be pretty lethal, as we read in the Two Towers!
