The fight before that, at the Gokage summit both did not want to fight the other. Even as kids Naruto had vastly superior endurance. Curse Seal Sasuke only barely won. Early-part-two Sasuke caught Naruto at a bad point (if they'd encounter him a few hours earlier Naruto's 4-Tails form would've broken him).

Not to mention, they mirror each other continually (Sasuke's MS, Naruto's Sage mode. Sasuke's EMS, naruto's Bijumode, etc).

Clearly Kishimoto intended them to be equals.
