 * The copying part in Sarada vs Buntan battle was the least believeable part of the fight because of the lack of the common logic. Visual-wise, it seems brilliant and even brings up the memories of part I Kakashi vs Zabuza water dragons' clash, but still, it makes no logical sense. I mean, we've never seen Sarada performing Lightning Release so far, and it obviously isn't her speciality nor battlestyle, while in Buntan's case, it should be both her speciality and battlestyle alltogether. Even if we discard the possibility of Kiba amplifying the power of the user's lightning techniques, due to Chojuro's statement about the sword being as powerful as its user is, Buntan's skills technically should've been no match for Sarada to counter them by simply copying the jutsu.

Sarada could very well have learned how to use Lightning Release to an extent by now. Sasuke learned Fire Release on a powerful scale before even entering the academy, and it's not even his affinity. Buntan's specialty was Lightning Release, sure, but Buntan isn't at the sort of level that would make copying impossible. Kakashi said he could copy techniques up to the difficulty of the Rasengan, and I doubt Buntan's techniques were that difficult it terms of complexity.
