In theory, Sasukes power is equal to that of Edo-Madara, or in its 'neighborhood', until he detaches from Susannoo to use Rinn & its techs. Therefore, Edo-Madara was owning everybody prior to that point where Gaara found a way to disable his Susanno, and just changed doujutsu and went on another rage. The basic point is all of his jutsu are so powerful and huge, theyre are few attempts to attack him much, and nowhere near 'equally'. I'd suspect Sasuke's to be deadly as well, and Kishi made it rain for the purpose of giving Sasuke acess to an abundance of lightening techs, to allow something other than only spamming Amaretsu varients.
