I don´t know if OP realizes this but one tailed Naruto part one got b7tch slapped by Sasuke, Haku, Zabuza, Oro,Kabuto,Akamaru -no tail-.. I say slapped cause he wasn´t even punched by those guys but actually slapped. Kakuzu was an S class bingo book criminal and you might have noticed extremely dangerous and experienced meaning the chakra issue (enhanced strength and a bit of speed) would´ve meant little if not nothing for him. Add Shin boy to the equation wearing an MS, fully functional or not and Naruto gets wasted.
One tailed Naruto or chakra cloak worked as a life saver, but never ever as a ninja tool for him. I´d use the cave man using his club Naruto version as a euphemism
Peace
