Kings haki is only useful against fodder, Luffy have kings haki yet he could still get punked by admirals whi don't have it. Kings haki is no argument for determining the strength of a character. Also Mihawk is the worlds strongest swordsman and Shanks is a swordsman so there you have it.shanks over mihawk but not by much. shanks is a yonkou, mihawk is not. shanks has kings haki and mihawk hasn't proven he does. he might but its not a canon feat yet so theres no argument. now if mihawk shows kings haki this thread will then be relevant.
