I think the battle with kaguya was more epic. I don't see why people say otherwise, people just bash kaguya because their fave madara got solo'd but does anyone really have a truly legitimate reason to hate kaguya? Madara may have caused an epic fight but remember Naruto and sasuke were still getting used to their powers. Since it's been noted that madara has far less chakra than kaguya and we saw how Naruto was able to briefly pound kaguya (albeit she gave him a spanking too), unrivaled strength would've made madara cry, with proper strategy, madara would've simply have been pwned. Naruto has his world shadow clone jutsu and we have seen that Naruto clones can hold off against the limbo. If kakashi gets both the MS then any move madara tries is getting beat. The time elapse for limbo to return would've been taken into account as well, with all this info the A team I mean team 7 would've beat madara as lot sooner than kaguya. Let's also not forget that sasuke could blitz madara or his clones, with the seals, it's possible to perform the creation of all things, not just fan fiction because when you think about the properties that each seal has it isn't that far fetched. I honestly believe with kaguya's abilities it gave us fresh environments. And new battle sights, kaguya is the strongest being in NV, madara wankers can't accept that all chakra is merely apart of kaguya, even madara, and madara was using HER power. Madara just had battle experience and kaguya is the true immortal and without the seals it's virtually impossible to beat her. To beat madara, Naruto could've just did what he did to juubito given the chance.
