@Rachin

That's fair, his most intense battles have been with him using his Sharingan.

But consider that he was fighting at Jonin level when he was 13. He had senses that impressed Minato, an intelligence compared to Shikamaru, etc.

He has proven his abilities that don't require the Sharingan time and time again. The Sharingan (until Kamui, that is) was just a tool; Kakashi was the man behind it. Even several Uchiha have noted Kakashi's prowess the Sharingan. It was his own skill that let him get to that point. He still has his own natural skill.
