at what point of the story? when naruto had sage mode sasuke had ms. i think a battle between sm-4tailed naruto against a cs2 sasuke would probably be about a draw since naruto cant use the fox against sasuke. jiraya would probably win against oro, but im not quite sure. the point why naruto and jiraya would win is that sasuke and oro never really had a strong emotional binding, they are both mainly lone wolves and therefore arent used to fight side by side.
How do you know Naruto can't use the fox against Sasuke, sure he blocked it that one time at Oro's base, but don't you think Pein would of supressed the fox against Naruto, I mean seriously the Master of the rinnegan created the Bijuu don't you think it could supress it to, this is just a theory but anyways.
Why say it would be a draw. You said sm-4tailed Naruto vs CS2 Sasuke. Then you turn around and say that the fox wouldn't work. Didn't you just contradict yourself
Anyways, if it came down to it, SM-4Tailed Naruto against CS2 Sasuke, Naruto would win.
In the Valley of the End Naruto fought against Sasuke, Sasuke was CS2 and Naruto was 1Tailed and it was a tie. Now imagine Naruto atleast 4 times stronger with the tails alone plus sage mode against Sasuke who only has his MS added to the equation, the math is simple
Naruto>Sasuke
