I wouldn't really consider sealing the Kyubi inside my own son a very good thing.
Hiashi was very cruel to Hinata and even degraded her strength. He practically gave up on her.
Orochimaru is technically not a father, so I won't count him.
It took a long time for Fugaku to acknowledge Sasuke's potential. Although Fugaku cared about Sasuke, I wouldn't consider him to be the best.
Shikaku never really expected anything from a slacker like Shikamaru, but he still showed him the way and cared for him.
I don't know anything about Inoichi.
Choza seems to care a lot for his son and even convinced him that he would one day have enough confidence to grow wings and become a man.
I choose Choza for sure.
EDIT: Oh yeah, and for those who chose the 4th Kazekage, you should really look at what he tried to do to Gaara. He is probably the worst father in Naruto. Period.
