How does sm help against Madara? Sure it increases their strength reflex and speed for a bit but that won't increase their chances of qinning by much at all, Madara's kyuubi covered in PS sliced like 6 mountains instantly, when narso and sauxe does that, we csn talk.
Nardo and Sauce defeated juubito with the entire Sa and gokaes and also hokages, and it was due to tnj, Madara xounters everything nardo has, samw thing goes for sauce, Madara's PS>>>> sausages in terms of power, same thing goes for full kurama and half kurama.
