I noticed that some of you don't understand the Naruto vs. Sasuke battle. I think it is very annoying that so many Sasuke fans say that Uchiha Sasuke is stronger than Naruto, and that he won the fight in the rescue fight. As far as I am concerned, this fight was a tie. The Rasengan vs. Chidori clearly was their last effort to end this battle, and the fact that Sasuke was still standing after the final explosion should not be interpreted in such a way that he won the fight or that he is ultimately stronger. The reason for this, in my opinion, are the side effects of the cursed seal and the kyuubi seal. Frankly, they are different. The cursed seal corrodes your body and slowly turns you into Orochimaru's slave which is the prize you have to pay to gain such power. Naruto's power has different side effects; his body gets tired and he can't move anymore if he used too much of the kyuubi chakra. That is what happened when he summoned Gama Bunta for the first time, he was asleep in the hospital for about a week. In the rescue arc, it was the same...Naruto was too tired to move. So do you know why Sasuke decided to let Naruto live even though he intended to kill him seconds ago? Because Naruto proved that he is equal to Sasuke. There was no winner, only survivors.
