Bioshock fans, which city is more amazing, Columbia or Rapture?

[Moren]

Columbia... the nicest place to live... so... pretty... enchant.... me... it's so wonderf.... WHAT THE HELL WAS THAT OH GOD 77, RAVENS, NUN!!!

I like Columbia more so far, because it's both a magnificent and horrid place and the more I explore it the more apparent its twisted nature becomes.
