Naruto need all the support in his battles/and kish protection inorder to survive a battle.People still consider naruto as overpowering and he cannot be defeated .Naruto without the Ninetail help is nothing and we all saw that in the war arc that the ninetail secretly giving chakra instead of taking it away from him.
Any way the uchiha have alot of chakra reserve because an non uchiha (eg kakashi )uses alot of chakra to use base sharingan and ms abilities while the uchiiha uses the sharingan with ease.
We saw sasuke battle orichimaru,dediara,itachi and killerbee one fight after the other and he was not fully recover then after he fight the kages a follow by the danzo and team 7.This show he had alot of stamina.I know karin heal but she did not give him chakra ,just close his wounds.
Itachi is known for killing his oponent instantly with his abilities and join the anbu ninja squad at an early age.
The uchiha basically BADASS because they master their taijutus ,weopanary,genjutsu and can copy alot of ninjutus at an early age with their sharingan and it pay off when they get older because they donot have to train much
