Wrong, Sasuke's chakra potency is what allowed him to match Naruto's endurance without relying on too much chakra, the higher the chakra potency the less chakra and stamina is required for powerful jutsu.
The chakra being powerful doesn't mean it uses less chakra. Look at everytime Naruto let the Kyuubi gain control...the chakra's he was using were enourmouns yet potent. It's the same thing with Sasuke.
Naruto chakra reserves are not only much larger than Sasuke's but also as potent as Sasuke's chakra as well. Add in the other bijuu chakra plus NE and he's the strongest there is....

uttahere:
Yes he has larger reserves BECAUSE of the kyuubi...but naruto's power is no where as potent as Sasuke. You can't find a single scan even suggesting that. I don't think you know the difference between Naruto's chakra and the Bijuu's chakra. Naruto uses Bijuu chakra to boost and extend his reserves. If Naruto's Chakra is a thin ocean of oil then Bijuu chakra is an ocean of water beneath the oil. Naruto's chakra isn't potent and of all the Bijuu The kyuubi's chakra is the most potent and the kyuubi itself said that Sasuke chakra is more sinister than his own
Denying facts doesnt prove what i said to be wrong dude :lol
Sasuke ask/stole chakra from Naruto
After Naruto had been fighting for days
Then Naruto fought him at the end of the series.
Naruto had been fighting for days and during that time the Kyuubi was replenishing his chakra. Please don't even begin to suggest that he was doing all of that from the reserves he carries around every day and if you belived that then sorry you're dumb :lol
So despite naruto starting before sasuke, being in more battles, and spreading chakra to others, sasuke still equals narutos best trait? Gotcha.
Yes. His endurance and stamina is the same as Naruto's. VoTE 2 proved that they actually were equal but they were acutally equal before. If you compare the amount of things Sasuke did from Susano'o, to Enton, to amaterasu plus his own jutsu you'll realize just how crazy his stamina and endurance is
