Sasuke's speed is instantaneous.
How can one be faster than instantaneous? That's like having more than infinite. It just doesn't make sense.
Naruto's KM speed was compared to Minato's FTG since all you see is a yellow flash. So Naruto's lower form moves at a speed that is instant. Naruto is the fastest in reaction, reflexes, and speed. Sasuke can only teleport instantly but attacking would be his speed which is lower than Naruto's speed+sensory ability and Sasuke still have to use his vision to see where he'll teleport to.
As for the Bijuus, Sasuke sealed them instead of use them to fight like Madara and Obito could do with full Kurama so his control is limited to only immobilizing them as of now or else there would be no reason to seal them plus a Yang Kurama was able to talk to Naruto while he couldn't talk at all when Madara and Obito were fully controlling his actions. Sasuke also doesn't have close to Naruto reserves while Yin Kurama can gather more chakra and Naruto have limitless access to natural energy so whil Sasuke's Senjutsu from the Sage runs out Naruto would only gather more. Naruto current have the advantage here since he didn't use the Bijuus Sasuke seal to fight either way, he has portions of their chakra already inside him.
Sasuke has EMS and Rinnegan, Hashirama DNA (boost in stamina), the little bit of chakra that Hashirama had left (100% that he used it up already in his fight since he used PS a good amount of time and Rinnegan jutsus would be costly if MS jutsus are), the jutsu Hashirama gave him which he said would be used on Madara who has his Senjutsu so most likely can only be used on Hashirama's Senjutsu, Sage Yin chakra. Naruto has his SM, Yin Kurama+portion of the other 8 Bijuu chakra, can combine both mode for Rikudo Mode (RM) which let's him fly and use the truth seeking balls, and "that jutsu".
