Naruto at this point can wreck everyone bar Kaguya, but I don't see him being able to fight off Obito. The only thing that changed from when they fought (prior to him being jin) is that his attacks became drastically stronger.
It's like fighting a hologram that has a sniper, so you then take steroids and get drastically stronger but it doesn't change the fact you're still fighting a hologram.
Not to mention Obito essentially had only half of his original power when they fought (rinnegan didn't do shit), the other half was being used against him (Kakashi).
Obito's visual prowess is at full power now so he gains the ability to snipe off naruto's head twice as fast because of both sharingan.
