I understand what you mean but I think many people misunderstand most Naruto fans when we say Naruto is the fastest..Well feat wise, Naruto is physically stronger than Sasuke. Naruto, in sage mode, was capable of lifting an enormous Rhino. That's at least a ton or more. Now considering that VOTE 2 Naruto is significantly and exponentially stronger than Pain Arc SM Naruto in terms of physical strength, VOTE 2 Naruto should be able to lift mountains with little to no effort, either using his own bare hands (which I doubt is possible) or the Kurama Avatar. However, Sasuke has no such feat in Manga or even Anime. Sasuke is factually faster than Naruto though, seeing how he can travel an instant speed. Instant meaning that he can cover any distance he would like in the same and constant fraction of a second. That means that if he wanted to get from Konoha to Kumo, it would take him the same fraction of time that it would take him to get from the earth to the moon. The same exact fraction. Maybe 1/100 of a second, but we don't really know how fast an instant is. Greater and more constant than the speed of light, that is for sure. However, I believe that where he can teleport is only limited to the range of his eyes sight. He can only switch places with things that he can see, and if he can't see a rock on the moon then he can't switch places with it in order to teleport to the moon. So even if his distance isn't limited, his range is. Albeit he can probably just use dimensional travel.
With Ameno Sasuke can get to very far away places earlier then Naruto.
The problem here is that Fast talks about speed right..
Speed = Distance /Time.. with Ameno Time = 0 since it's instant thus making Speed = ∞ which isn't a number
so when we're considering speed Naruto is indeed faster but Sasuke will always get to far away places earlier because instant Ameno..
near places is a different story as Naruto has near infinite speed at full power ( RSM with 9 bijuu)
Since we've established that Ameno isn't speed, we can compare them without using Ameno and you'll realize Naruto is indeed the fastest
