Emperor Zurg would have won that last round but he had no comments to leave. So please comment!

I don't know anything about Zurg's parental skills but Buck is a horrible father. He was embarrassed of his son and made him feel like he was just a mistake.

I completely agree with @KataraLover. He just ignored his son until his son did baseball.

From what we know about Zurg he abandoned Buzz and then wanted him to join "the dark side". Buck on the other hand loved his son, he just wasn't good at expressing his love.

He does not care for his son much, if not at all. Good parents never deliberately neglect their children

I agree with cruella

He literally wants to destroy Buzz during most of the film. While Buck isn't a great parent, he didn't want to destroy Chicken Little!

^ yep

Buck was a confused father. He cared for Chicken Little, he just didn't know how to express it or how to deal with the 'sky falling'. He did kind of neglect him, but he never meant to be harsh. I think Buck redeems himself by the end of the film because he truly did care for his son.
Whereas Zurg, though awesome, is not the best father. He tried to destory Buzz, and then wanted him to become evil. He also hadn't really spent anytime with Buzz, because Buzz didn't even recognize him as his father. At least he does the father/son sports thing at the end, lol.

I'm judging off the only few minutes where Buzz knows he's Zurg's son, where Zurg reforms.
