I really appreciate moments of Clark contemplating the world
It's obviously an elseworld story, but I think it'sn portrays the introverted side of Clark really effectively. I don't like the idea that Clark is "an alien", but the idea that he is appreciates things at a distance is really core to my understanding of him. That's why I love the Fortress of Solitude.
Of course I also love the relationships Clark Kent has with random people throughout Metropolis
