Now your putting words in my mouth. Kakashi has way more experience, he knows his student and he fought Sasukes brother, itachi twice.
I think kakashis battle experience alone makes him smarter. Sasuke could have been as dumb as a brick and still won. He could have spammed 1 technique, susanoos arrow, and still won. Even with kakashis tons of exp, thousands of jutsu and smarts, he just had no counter for 1 jutsu.
Sorry for putting words in your mouth.
Kakashi would have defeated Sasuke if he was dumb as a brick. If Sasuke was dumb as a brick, he wouldn't know how to use Susanoo, or its arrows. Only a combat genius/ someone with high intelligence would be able to effectively use such a technique. Combat experience has nothing to do with combat genius. Let me use this example:
Say you're in a fight with someone who has a gun, and you are a trained soldier, and your opponent is a thug, not trained in combat. On an even playing field, you would whoop him. But let's give you a knife, and him a gun, and quite a good distance between you two. If he knows how to use a gun properly, chances are hes going to beat you. Making him smarter in combat than you, because he brought a gun to a knife fight, and knows how to use it properly. (Power+Intelligence)
Now, if he doesn't know how to use it, he misses his shots/ you dodge the bullets, due to your training, and you successfully knife him, you are smarter than him in combat, even though he was more powerful, you still overcame him. (Intelligence)
If that doesn't make sense, Kakashi is more experienced than Sasuke, But Sasuke is smarter combat wise, because he knows more techniques, (more powerful ones too), and can use them effectively. If Sasuke spammed Chidori like he did as a kid vs Kakashi, he would have ended up dead. Brute Force will never win. But Intelligence AND brute force, will always win over just intelligence.
