Anakin/Vader was also conflicted and not 100% resolute. Kenobi was a master of a lightsaber form in a time where saber duels were rare. He almost got cleaved in two by a decidedly anachorist swordsman the first time, he got caught off guard and pwned by powers the second time. Though far from a slouch, Dooku was by no means the best jedi or sith.
Revan is overhyped, but his swordsmanship mastery was in a time where saber duels was a common thing. His powers were more diverse (which means improvisation), even if he wasn't the most powerful ever. Would not have the same issues Anakin did.
