Re: Final Battle between naruto and sasuke.
Sasuke can use a normal Fire Style jutsu to prepare the Kirin. The Kirin also uses no chakra what so ever.

Kirin is the fastest jutsu in the series, or at least its faster than any jutsu Naruto can use.
Naruto has Sage mode and Bijuu Mode, but Sussanoo alone can stand a equal fight against that. ( Shown by Madara )
Sasuke can summon a Hawk, and possible more summons we don't know about..
If Sasuke uses Amaterasu to prepare for Kirin, then he has shown that he uses close to no chakra at using large amount of Amaterasu.
