Madara had SM for bijuus. Even nagato via pein could restrain SM jiraya with just one rod. They were immobilized due to pressure points.Pinning down Hachibi doesn't equal to Madara's outer path feats. Madara's outer path, restrained 9 Bijuu at once and pulled them inside Mazo, it can manifest Black Zetsu, it can effected the vital Chakra points and immobilize the movements of people with powerful Chakra. That is far above Obito's and Nagato's.
Sasuke's Susanoo arrow couldn't damage it, and you're telling me a swing would?
Learn to discriminate b4 naming madara stronger, Obito near death overpowered his chakra after all.
Its not about destroying rods it about getting them out. Just hit them from the side they will come off as most of it is out anyway.
