Sakura's is a book nerd IIRC. She's probably a walking dictionary, but has 0 battle feats of intelligence or wit. And she makes stupid decisions like biting Zaku's arm instead of attacking, trying to run into Haku's Ice Mirrors, attempting to kill Sasuke alone, and she wears a skirt into battle with hot pants underneath and hasn't invented a single jutsu in the entirety of her ninja career. Pretty stupid imo.
Hinata answered all the questions on the Chuunin Exam written test by herself like Sakura. And Hinata knew Naruto needed help and charged Pain to help. And she saved the world again by cheering Naruto up after Neji died.
Looks like Sakura is smarter if you need a nerd to do your homework, but Hinata is smarter in practicality and saving people.
