Sasuke is even better. Kakashi lost the power of Shalingan after the death of Barrel Wood (recovered his ordinary eyes, although the knife marks were still there) and changed back to his true self. The tie is still there, but the knot is untied, which is also a good thing. Sasuke, Sasuke has gained the power of Indra, plus the power of kaleidoscope sharingan and smiling face, which is amazing.

Kakashi won by skill and intelligence (tactics), but Sasuke is not only a talented ninja, but also has the strength beyond orochimaru and even ferrets. His strength can be described as the rhythm of 60 (one kaleidoscope of Saringen 70, two kaleidoscopes of Saringen 90) to 90.

Although Kakashi is the sixth generation of Huo Ying, his strength is not the strongest, just like Gang Shou, but Murakami who can win the hearts of the people is a good Huo Ying, but Sasuke can't.

On martial arts, Sasuke is powerful, but thesis+martial arts, Kakashi is even more powerful.
