Let's not forget that Sakura, a 16 year old girl, managed to have a powerful S-LEVEL technique(Shizune couldn't) and god knows what more, without being part of a super powerful clan with pre-existing powers, which is admirable.
She's been healing people the entire war, let alone storing chakra for her duper-awesome seal.
let's not forget that she (with the help of chiyo) defeated sasori, an s-rank missing-nin, while using HALF OF HER CHAKRA
