To me, the difference would be that Naruto and Sakura have a different relationship than Naruto and Hinata do. In the case of Naruto and Hinata, we don't know whether or not Naruto has any feelings for her that are beyond friendship. In fact, we have to come to the conclusion that he still loves Sakura because, so far, he hasn't stated otherwise. In Naruto and Sakura's case, the person in question is Sakura. While we know that Sakura still loves Sasuke, it's also a cannon fact that Sakura's feelings for Naruto have changed.
So, is it bias to say that the same moment occurring between Naruto and Sakura would be more romantic than it was between Naruto and Hinata?
Personally, I can't really say because it depends. Why? Because Naruto and Sakura have a closer relationship, so it's hard for me to say how Naruto would have reacted if it was Sakura instead. If Sakura was saying the same words as Hinata (basically it was just a pep talk) then no I still wouldn't declare Narusaku canon from it, especially if Naruto's reaction was the same as the actual chapter. But again...if Naruto's reaction was like "Sakura's holding my hand" and if Sakura had blushed or something (no straight face about it at all), then yea I would have a different reaction and no I wouldn't consider it biased. If her reaction was really normal about it and there was a different reaction then yes it would be biased to me. It's really hard to say >.<
