in the obito fight he adjusted his chakra to naruto to match his frs attack, he had juugo lnfuse his senjutsu chakra to him so that he could fight, and overlapped his perfect susano with the kyuubi armor do you call this little battle sense? lol also itachi repeatedly told sasuke not to kill kabuto so he couldn't fight to his full potential so no...
Matching chakra ratios is something Naruto and Sasuke have been doing repeatedly, since they were kids. And Naruto deserves exactly the same amount of credit for that feat since it's a shared feat. Although that technique had literally 0 effect anyway, since ninjutsu doesn't hurt Juubito.
Susano Kyuubi was legit and Sasuke deserves credit, however it is a technique that Madara invented in the first place.
And like I stated before, Naruto is superior in knowledge and practice of senjutsu chakra. The Juugo point isn't really a beneficial point to bring up since Sasuke is still a relative beginner at Senjutsu compared to the likes of Naruto, Juubito, Hashirama, and Rikudou Madara. Sasuke is probably closer to Minato's level of Senjutsu. Or Jiraiya's level, since he needs a partner (Juugo; elder sage toads) to use it.
Naruto
figured out the fact that Juubi-jin forms are weak to senjutsu/natural energy.
I'm not saying that Naruto is smarter, but for Sasuke's intelligence, he has been performing slightly under expectations during the first part of this war. Although I believe Sasuke's comeback to this fight will be just as epic as Naruto's.
