I'm actually glad that Hinata was chosen for that. Hinata was trolled there.
Hinata: "I won't let you lay a finger on Naruto!"
Pein: "Okay, I'll lay one on you then"...BOOM.. One hit KO.
Hinata's foolishness -Naruto is devastated. He loses composure and almost ends up losing himself to Kyuubi.
This was against Pein remember.
What about Sakura? RtN-Similar scene, against a tougher opponent, Madara/Obito.
Sakura: "I won't let you have Naruto!"
Obito: " This girl stands no chance against me"
Obito: " Damn! This girl is strong and ruined all my plans!"
Sakura manages to hold her own and buy Naruto time to regain his memory and fight as himself.
So, who got the better scene?
One more thing, I'm also glad it was Hinata there because her confession was done there. If she hadn't confessed there but instead done so near the end of the manga(especially after 615) not many NS fans would feel easy, I can tell you that.
When Sakura found out that Hinata loves Naruto she felt kinda jealous.
