so basically your entire point and this joke of a thread is banking on some slight edge advantage with featless adult obito and somewhere in your deep thought process mind you came to the conclusion it is enough to out weight what itachi has done. "kakashi was a jounin lvl " that jounin couldn't even trash 1 fodder jounin without kid obito's help. itachi casually taken down 3 uchihas at once. that feat alone is better than any cqc feat i've ever seen in any kakashi period, and not getting hit by B from behind while focused on kcm naruto is far more impressive than that entire hand2hand combat with obito. which btw is completely exaggerated in the anime. it was ninja tools that gave kakashi the edge against obito, and if you wanna factor in weapons then itachi definitely win.
enough said
