@Flatzone he's obviously not walking around through dimesnions, since he was battle-rready when Kinshiki ambushed him.

And of course eventually it exhausted him (though not to the point that he couldn't still use Ameno, so there's that), but he'd been doing it far longer than Obito had.

Yes, Naruto revived Obito. So Obito is revived by Naruto empowered by Hagoromo, with Hashi healing SP power. Yeah. He was going to die but he wasn't close to dead at the time.

And both Hashi healing and Sakura Byakugo healing wasn't enough. It's legitamately so obvious from Sasuke even opening one portal compared to Obito just opening one portal that Sasuke can do it far easier.

And Obito is about as efficient as can be with Kamui, so it's not a question of effiency.

So that means Sasuke has more chakra than Byakugo seal Sakura, who has more than half of Naruto's chakra art this point. Sasuke wouldn't grow from having less than half of pre-Hag Naruto to having more than half of post-Hag Naruto unless he kept the boost Hagoromo gave him.
