I seriously thought that I would be the only one to list DCEU among the best versions of the character. Glad to be wrong!
By the way, while we are on topic, I was checking out my shelf and spotted Secret Identity, which was a very interesting take on Superboy Prime and the character of Superman in general. I would call it one of the best versions as well, because that Clark Kent was a normal human for the most of his life and when he got his super powers, he handled it like a true Superman.
