Kaladin, hands-down. For me, it isn't just what the character's personality is like, or how important they are, but how well they're written. Kaladin feels real, not this odd OP hax guy, but someone who develops slowly, but steadily. Book one's Kaladin really showed him coming into his own. That was the culmination of a long, long ride, imho.

Best moment: Kaladin turning super soldier and coming to Dalinar’s rescue /thread
