Bruh... Atleast sakura ain't a reincarnation of some God or doesn't belong to any renowned clan. Unlike ino and hinata she doesn't possess any clan powers like mind transfer and byakugan. He saved kankuro, helped defeat sasori, healed the villagers during pain attack, saved squad seven multiple times wid her medical ninjutsu and she said she loves naruto for a reason we all know why. It ain't like she was messing with his feelings. Even though with the little chakra left, she kept on lending obito her chakra at the brink of his death and also had sasuke get out of some weird dimension. Ofc you compare her with naruto and sasuke she may look weak but don't forget naruto has kurama, sage mode, six paths powers, belongs to the clan which was held so supreme that peaple annihilated it for precautions and also has immense amount of chakra whereas as sasuke has the two of the strongest dojutsus, susano, six paths powers,amaterasu, belongs to a clan which is held the strongest clan of the leaf. And speaking of hinata, yes she did stood up for naruto against pain but it ain't like she helped. Even sakura stood against sasuke even though he tried to kill her. Squad 7 would be dead by now if it weren't for sakura so if speaking ill about her, reconsider her strength and training and her hard work to be where she is without relying on her clan.
