Broly(Paragus), Gohan(Goku), Trunks(Vegeta). 

Broly has known/lived with his father the longest than any main cast character in the series. 48 years with Paragus and no body else, except Bah. Paragus was Brolys provider, care taker, trainer, father, and teacher. First person Broly ever loved coming into this world was Paragus. Despite how badly Paragus treated Broly, you can tell Broly deeply loved his Daddy. Paragus’s death also gave us a legendary (pun intended) SSJ transformation. 

Gohan loves Goku, but we have to realize that there’s that 7 year absence. Why Goku never called his family during those 7 years, or any form of communication is beyond me. Nonetheless, Gohan still was ecstatic to see his Dad return, but now (in super) he’s carrying on with his life like nothing happened. There’s no urgency to spend time with his Dad. It’s more like Goten and Gohan made peace with how things are with their family and normalized it.

Trunks absolutely loved Vegeta. They showed a father son relationship you’d expect from the two. However, Trunks situation is weird. He never met Vegeta before, only heard Bulma talk about him, but Trunks still had that curiosity and longing to know his father, spending 90% of his time in the past lingering behind Vegeta. Not really knowing what to get out of this? Bulma sent him to the past specifically FOR Goku, yet Trunks chose to spend the entire arc with Vegeta, I guess that boils down to love? 

**TLDR:** Broly loves/loved his dad the most. 

We always talk about the “best dad” how about who loves their dad the most ? (read body text)
