Sasuke absorbing bijuu chakra with preta path is NOT the same as Naruto using it. Kurama and Naruto's chakras are fused into one. When he uses kurama's chakra, he uses his own at the same time. What you're saying basically states Sasuke can absorb nature energy as well, which we know he can't.
And what's all this talk about the Sharingan like it's so unique?? Some people are proficient jinchuurikis the same way a few people like Kakashi and Danzo are skillful enough to use the sharingan at a Uchiha level..Or Nagato being able to spam Rinnegan. If you notice, the strongest bijuu's jinchuurikis just happened to be Uzumakis..None of them suffered side-effects like Gaara, and the they don't fit the probability chances of someone being able to handle bijjuu charkra, it was implied in Bee's flashbacks
Oh and regarding Naruto's talent, he inherited his mother's chakra (strong enough to tame Kyuubi with her chains on verge of death.. no talent my ass). His chakra control surpasses everybody else's as seen in Shinobi war, TSB and use of 9 bijuu KKG without practice. His Uzumaki lineage gives him large natural chakra reserves that allow him to spam Bijuu power.
If you noticed, Bee and other Jinchurriki haven't been shown to spam bijudamas and full beast form like Naruto. And controlling Kurama's chakra isn't just some walk in the park, if Sasuke couldn't get rid of his hatred how the hell would be handle the bijuu's will ? Yamato also implied this when he was surprised Naruto could handle bijuu mode against Orochumaru. It's not a coincidence that 3 Uzumakis in a row were the strongest bijuu's container. Uzumakis were mean't to be jinchurikis the same way Uchihas and Senju were meant to tame them, I'm a massive Sasuke, Madara and Uchiha fan but give a clan credit where it's due.. U_U
