In short, kakashi stomps. As others have said, he has better experience at the same age, based on feats. Better mastery of his sharingan. Better skillset smarter and the stat difference isn't in sasuke's favour either, even if he has slightly greater stats it doesn't matter, kakashi can react to him just fine and his better skills/experience grant him better effiency of movement and better counter-attacks.

kakashi can easily beat sasuke using sasuke's anger against him. Kakashi has shown to be proficient in shit-talking and goading his opponents. Kakashi won't take initiative. He lets sasuke use fireball jutsu first, and he copies it and counters it. sasuke tries another fire style, kakashi copies and counters it with the same jutsu. Sasuke starts to get irritated. Tries to use shadow shuriken jutsu, kakashi blocks with his earth style mud wall. kakashi also takes this time to do his famous clone switcheroo.

Sasuke tries to  blitz kakashi using chidori as he runs past the wall and engages what he doesn't realize is kakashi's shadow clone in taijutsu. But due to sasuke's frustration his taijutsu is too telegraphed. kakashi grabs him in a choke lock. then the real kakashi shows up with chidori conjured and blitzes sasuke at his top speed using the opening his clone created, before sasuke can counter. The end.
