Who's love was stronger?
Naruto's love for Sakura or Hinata's love for Naruto?
Before this crap ending I would've already known the answer but now I don't know what the hell to believe. Hinata had more of an infatuation while Naruto *had* more of a mature love for Sakura willing to step aside for her own happiness to get with some other guy.
Meanwhile Nardo's newfound "love" for Hinata is opposite; he won't tolerate competition from Toneri or any guy who whisks his Hinata-sama away and will even get mad at Hinata (the victim) herself.
Also Hinata was too much of a dumbass to realize that Naruto already had eyes for another girl. Either that or she didn't care.
Naruto's love for Sakura, since he realizes EASILY why he loves her, while we didn't learn the real why to Hinata loved Naruto outside of how he inspired her.
