You are a Sasuke Fan Boy troll...
But Base Naruto meaning he can't go into SM, then yes probably high Jounin level, with SM much higher
He can first of all out last any Jounin out there, he has so much chakra that he could last 20 times longer than anyone else, plus you are saying Sasuke took them on, but that wasn't base Sasuke, base Sasuke is no Sharingan like Naruto can't use his Bijuu or Sage Mode.
RasenShuriken is very hard to dodge because it can be held for as long as he wants and it expands.
Kakazu wasn't something that can be thrown aside because Hidan who was much worse than him took out Asuma who was quite strong and a Jounin, and Kakazu also was fighting Naruto when he had just learned RasenShuriken, so if he was fighting him after he had mastered it, he would have hit him the first time. And is there a single Chuunin who could stand a chance against Naruto? No... Sasuke and him have always been equals, even in base mode as Naruto would have beat Sasuke's chidori if he wasn't aiming for his Headband. Also lets take Neji or Temari, could either of them beat Naruto? Nope. There is a lot of proof that he is high level Jounin level in base, just like Orochimaru, Jiraiya, and Tsunade would be Jounin in base mode. Without his snake transformation stuff, sage mode, and regeneration stuff.
