Of the choices on the list, Peter Griffin is by far the worst father. I mean, hell, he actively hates one of his kids for seemingly no real reason.
All of the other dads listed have flaws, sure - but at least they're trying their best to be good fathers. All Peter cares about is Peter.
As for which one of them I'd say is the best dad? I don't know. None of them are particularly great dads... but I think Homer Simpson is probably the most realistic. Pre-Family-Guy-influence Homer Simpson, anyway. Back before they started to mimic Peter's antics in The Simpsons, Homer was actually a generally decent father. Y'know... except for the mutual strangling gag that they used to do from time to time between him and Bart (to this day that recurring "joke" seems to not only come out of left-field, but run completely counter to Homer's established character). He's the only one that seems to genuinely feel guilt and remorse whenever he does something wrong or upsets his kids, and he's the only one whose emotional support whenever they're hurt or feeling down seems to actually be from the heart. He's also shown time and time again that he wants the best childhood for his kids, and actively participates frequently in their hobbies.
