Let's see.
Naruto - Has been there for both Boruto and Himawari since their birth. The Uzumaki household in the Boruto Movie is consumed with photographs of the entire family (all the way back to Naruto/Hinata at 19 with their orange sweater and purple skirt outfits from the Last) dating, pictures of the Boruto/Himawari as babies, family pictures we haven't seen, single shots with parents, and a lot more.
Clearly Naruto was an amazing father, you even see that at the end of the Last. The problem started when he became Hokage, and he had to priortize the village, which mean they had to face struggles. Though he always tried his best as a dad. If he could not make it personally (since it was stated multiple times that being the Hokage meant not taking any shortcuts, which means he wouldn't allow the shadow clone to do all the work for him). Though he does use them, because in the Movie the Hokage not only sits behind a desk all day, the village has Naruto doing mundane activities 24/7 which puts an enormous amount of stress on his body. In fact the animators put emphasis on Naruto's bodily problem itself where he was sleeping in the office due to the lack of it entirely (they gave him really dark circles under his eyes). Because of that he destroyed his daughter's birthday cake. Though towards the end of the movie he made amends to his family and is now there for them, cutting back on Hokage work for the family when needed (or at least that's what is being implied).
Sasuke - Clearly Sasuke's mission has held him busy for an ?? amount of years since his child's birth. Though, the main problem that I detest the writing of the character itself is how the mission was portrayed. Sasuke has absolutely done nothing since his meeting with the Kage's, in terms of finding evidence to his hypothesis, and fighting enemies. He has been searching for these threats for years, only for them to appear in the Chunin Exams where he finds a scroll he can't decipher without Naruto's help (In the Movie when Naruto became Hokage, he made a secret unit for these kind of measures. Hokage Naruto FTW). Despite this, Sasuke has not contacted his family in that period of time at all. Though that does not include Naruto who he has kept in contact with periodically.
The thing is, Sasuke isn't a terrible father though. He just makes big mistakes that overshadows his character. It isn't his fault, but how Kishimoto wrote problems that affected him. I mean him not even knowing what his own daughter looked like ... he was literally about to kill her until she broke down and cried his name. What the ****?
But from what I have seen with Boruto, Sasuke is clearly a great guy, but like I said before mistakes overshadow their greatness here. Overall I think Naruto is a better father, but realistically I think they are both great dads. That doesn't change how I feel with Sasuke not contacting his family in over a decade.
I would care less if Kishimoto had Sasuke fighting enemies or finding evidence, but nope. All that shit happens years later when the children are grown up. Like really Kishimoto? He could of had Sasuke leave for his mission that same year and nothing would of changed. The most Sasuke did for the world was present his finding after his redemption journey in the Hokage flash back, ever since he departed for his secret mission it has all been for nada.
