Hurin is said to be the greatest.IIRC Turin is actually described in The Silmarillion as "the greatest human warrior." (I paraphrase.) Unless that was his dad, Hurin.
You forgot the most ridiculous of all Malazan warriors, Anomander Rake, who is what would happen if you got a 14-year-old to eat a whole bucket of halloween candy and then try and come up with "A BETTER ELRIC".I don't think anyone has yet mentioned the badasses from the Malazan books, so I will throw in these three-

They're definitely unique. It's a strange mixture of cool perspectives that aren't always well-explored in fantasy, some of which are done well (undead cavemen, for example), some of which serve to illustrate why they're rare attempted, some pretty cool war scenes (which sometimes feature excessive or gratuitous sexual violence though, note), and an awful lot of really cheesy power-fantasy which, when you know all the most "XTREME BADAZZ!!!!" characters come from their home 1E>GURPS game really colours how you perceive them. For me it completed it's final shark jump (of many) by introducing a character somehow really significantly worse than Anomander Rake, Tehol Beddict. If Anomander Rake is a sugar-rush early teens too-much WWE take on Elric, Tehol Beddict is a particularly smug male college sophomore's idea of what "badass" looks like after he's taken like, Economics 101 and watched too many episodes of House (or the like). Tehol (what a name!) is a dressing-gown-wearing, get out of bed at noon, smug, superior, condescending, snippy dude who inexplicably all the ladies love, and who is also, in ways implausible for even "xtreme fantazy" like Malazan, is so "good at economics" that he can rapidly but without magic cause economies to crumble and so on. He also allegedly acts like a dumbass to conceal that he is secretly the smartest guy on the planet - in actuality he mostly acts like a guy who spends too much time on Reddit - and as a bonus he is of course totally ripped despite doing zero exercise.Yeah. Nothing I've heard about the Malazan books makes them sound in anyway an appealing read.
