The two most hated female protagonists of anime, Kagome and Sakura! IMPORTANT: The question is NOT who would win in a fight, the question is who is hated by the anime community more? Sakura or Kagome?
Okay, now for my conclusion.
Sakura Haruno is a character of Naruto who doesn't show as much potential or strength compared to the other characters in the series. Kagome Higurashi is a character of InuYasha who doesn't contribute as much...how would we say...importance to the storyline as the other characters.
Sakura Haruno is a member of Group 7, who has already lost Sasuke Uchiha and is functioning fine. Kagome Higurashi is an important member of "The InuYasha Six", even though her basic job is to sit around and cry out everyone's name while they're battling.
Sakura Haruno isn't strong (face it.), but miraculously becomes almost as powerful as Hokage Tsunade in a couple years' worth of training. Kagome Higurashi has mystical, yet not invincible, powers from the start of the series, only discovering them later on.
What I'm trying to say is, Konohagakure, Kakashi (and Lee and Naruto, over years of mental therapy), and "Naruto"'s storyline, can carry on just fine without Sakura Haruno. The current time era, apparently, couldn't carry on without Kagome Higurashi, who's main job is to save the earth from the wrath of Naraku and the SJS.
In conclusion, I believe Sakura Haruno sucks worse, even though she would obviously win in a fight against Kagome Higurashi.
