Itachi. Both were prodigy's in their own way, but Itachi has more control over his sharingan. Also Sasuke almost lost and he is stronger than kakashi. Kakashi may be able to use mangenkyo, but I dont think he stands a chance against ameterasu, tsukuyomi, and susano
You're forgetting that the question says if they both never got their Sharingan.
