What makes him better? Let's look at his qualities. On the inside, his morals and character are credited to humans: the Kents. On the surface, his powers make him strong and intelligent. Being smart and powerful alone are frequently characterized as insufficient when it comes to superiority because there are others with Superman's same abilities or similar abilities who abuse that power. So, it's what's on the inside that sets him apart and what's on the inside is the result of humanity's influence on him. He is not Jesus Christ. He is not a god. His whole mission is about inspiring humans to access the power within so they can join him in the sun. Join him, not look up at him from below.

They’re my magnetic north, if you will. They’re the WHY of it all. […] The world needs them more than it needs me. […] They’re special. I think they were all meant to do great things. Maybe greater in their way than what I can do. — Superman
