Gotta go with Naruto. He's busy being Hokage, but Heaven knows he tries, even if it's with clones, he's still trying to make an effort. And it seems he was around his kids alot before becoming Hokage. Then when he took over, he had less time, which Bolt hated.
Sasuke isn't horrible. I think he does love Sarada, and it seemed the short while he was home, Sarada was happy, and sad to see him go again. So he apparently wasn't an ass while he was there. But I still think Naruto edges out. And he's probably more demonstrative with his family than Sasuke.
