Naruto only talked to Hinata in an actual conversation about 4x in the whole manga so how would that be a good couple? 1st time was when she offered him her medicine in the Chunin exam, 2dn is when she talked to Naruto before he fought Neji, 3rd would have been here but she fainted without talking
Naruto never learned anything about her from her except that she loves him and her ninja way which both were in Pein arc and the war arc. Naruto learned about Hinata past from Neji during the Chunin exam. Sakura been there for Naruto for a far longer time and has shown to have feelings for him and we know he has feelings for her.
