Who was the superior protagonist?

[Example]

I'm not really a fan of either one, but I prefer Zack out of the two.

I have nothing against more complex protagonists but I feel like they didn't do it well in Cloud's case.

Care to elaborate why you feel that?

How did you get through Crisis Core then? Because Zack's moodiness gets WAY worse than Cloud's. That's why I couldn't finish. Happy and bubbly protagonist became eternally depressed and it was terrible.

Zack only gets depressed once you fight with Genesis for the first time and lose Angeal. After the time skip, he's actually back to being his cheerful self up until the ending. It helps that Gloom Cloud overshadows whatever moodiness Zack can have, and I was honestly more disturbed by Aerith being uncharacteristically gloomy in the game.

Did that actually happen in CC? Dear god, did they get ANYTHING right in that game?
