1. He is well respected, unlike Cronus. If he is respected, this means he must have done good deeds in order to obtain respect.
2. He did not sit on top of his wife like his grandfather, Uranus, and allowed Hera to have children. He may have had affairs with other women, but he treated her better.
3. He didn't have to eat his own kids to keep his position as a leader, and he is undefeated, showing he is more powerful than Cronus. Because he didn't have to do something so drastic, and that he is stronger, he fits a leadership role better.
