I stated him being faster in the scenario vs kaguya as seen in the OP. Naruto with his divine speed(Striking & Running) and superior reflexes and senses will always be faster than sasuke with his S/T(Instant), inferior striking speed,reflexes and senses.
Nope. Both have displayed similar reflexes. The only thing you could argue is RSM Naruto having a higher Shunshin, but all of their other stats rival each other:

Both combat Madara's Limbo clone at the exact same time.

Both rotate and complete their strike at the exact same time and are also equidistant to Kaguya as well.

Both complete their strike at the same time and lunge forward at Kaguya at the same speed once again.
How can people even be so dumb as to think sasuke could ever compare to Naruto in Speed in it's entirety.
I find it entirely baseless how people say RSM Naruto outclasses Rikudou Sasuke in speed. The only stat he surpasses him is in Shunshin speed, but their other stats are entirely the same or at least on par with one another.
