It was specifically shown (and stated) that she got power, her chakra became purple when it was blue, and she was able to share it around like Naruto can, also, she can fly.
The blue chakra was shown on the Anime, from Databooks, and from colored pages of the manga, Kishi has shown we know the chakra of some characters and some techniques are not the same color that the anime portrayed them.
It was never specifically shown or stated that she got Chakra from Hamura transferred to her, absolutely nothing, she said, and I am quoting "Hamura's chakra flow within me
too", so more people have it.
Also, in order to touch the Tensigan she said that "Only someone with Hamura's
blood can touch it "... otherwise It would drain your chakra. But Naruto (who hasn't Hamura's blood) could touch it without suffering the consequences using Hinata's chakra, meaning that regarding to Hamura, having his blood or his chakra means the same. To finish, Toneri confirmed Hyuugas have inherited Hyuuga's blood, meaning all of them have his chakra.
I am going to skip the part of the flying, It's just too... I am going to skip it.
She was able to instantly recharge a basically completely drained Naruto all the way to BSM mode.
It wasn't completely drained, great part of his chakra was with Kurama, who was fighting a giant golem, so his chakra pool was already significantly reduced. Neither was stated that Hinata completely recovered his chakra pool, we only know she gave him enough chakra to perform one cloak, not more, not less.
One cloak to me is not impressive, Bijuu level chakra was able to perform thousands of cloaks in War Arc.
The only reason why she didn't seem all that powerful is that she had weak techniques, if she actually trained with her powers and got new Jutsu's she'd be ridiculously strong, but anyway, she still negs Sakura easily.
Low diff.
It's irrelevant indeed, she has no impressive offensive feat with it anyway...
I consider, just like Narutoverse does, that Sakura is a greater Kunoichi, that's why she was already a Jounin in The Last. Only her and Shikamaru were promoted to that category by that time.
By Databook 3 we know Sakura is faster, smarter and has more stamina than Hinata.
Coils blocked by Gentle Fist can be unblocked by releasing chakra from Byakugou, just like Naruto released chakra from the Kyuubi to unblock the chakra points sealed by Neji's 64 palms.
Sakura only needs to land one hit.
This is my personal opinion, I respect yours, except the part of the flying skills, sorry.
I'd rather leave this here if you don't mind...
