I'm neither a fan of Hinata nor Hinabi, but this thread has started stupidly and so far has been staying just as retarded. Like really, you're trying to compare Hinata, a character that's been around since the beginning with various character development arc, and Hinabi, literally have 0 manga-fight scene thus far, and have far less screen time anime-wise, the argument in itself lacks evidences and sufficient relevant information as we haven't seen Hinata in action since the Ninja War. And even if we're to ignore that, we'd be comparing a supposedly genius and someone who tries hard to accomplish something, Hinata was never meant to be a genius, she's meant to be of a weak beginning and tries harder and harder as inspired by Naruto, while Hinabi is supposedly one of those genius by birth (more or less), maybe not like Neji or Sasuke, but still a genius, so comparing Hinata with Hinabi just kinda destroy the whole point. And then, there's the fact that Hinata made up for her inability to perform certain Hyuuga's powers by inventing new jutsus, which kinda gives her point over Hinabi, who's just another genius Hyuuga, since Hinabi so far is just more or less a worse-by-comparison-female-Neji. And at least Neji is more interesting because he has a background of being the branch house kid who was the best Hyuuga of his generation, Hanabi is literally JUST another Hyuuga, with almost 0 character development and 0 screen time before now.
P.S.: to the people who complains about Hinata's fight with Pain, er, put Hinabi in that scene, do you HONESTLY believe Hinabi would have done any better? Like really? Real-f***king-ly?! Put anyone besides Naruto (and the bosses characters) in that scene and they'd all get bloody murdered without even scratching Pain.
