Shin had the element of surprise against Sasuke, he randomly attacked him,still got owned,and Sasuke was shocked to see someone wearing clothes with the Uchiha crest on it, and have the Sharingan.
Naruto had the element of surprise against Shin,and knew he was an Uchiha,with a Sharingan,yet despite going BSM, he still got away from Naruto.
You keep misintepreting my comments. When did i ever say it would be hard? All i said was Naruto could not counter as easily in base - he could counter easily,as i noted earlier with using Clones but that is not as easy or quick as using chakra hands.
