I have a hard time with this one because there are so many versions of Krypton that I like, so I tend to favor the amalgamated Krypton from Post-Infinite Crisis simply because it has all of the stuff I love, but none of the stuff I don't. Basically, Buffet Krypton. Not as good as a singular vision coming from a great creator, but rather a collection of great concepts that any creator can use and build upon.

In terms of Jor-El, I really like Brando's potificating, but I'm also partial to TAS Jor-El's more man of action approach. I like to view them as older and younger versions of the same guy.

I like the aesthetics of Byrne and Snyder's Krypton a lot. The mad science experiment gone bad on a planetary scale.

Morrison's Krypton is the one where I'd like to party.
