I don't love either, but I prefer the bottom one. It's straighter, and I like the contrasty thing of the lights on the dark background. Plus, you can't see the less-attractive industrial-looking buildings very much in the darker ones.
Most definitely the bottom one
Well, that didn't drum up as much feedback as I might've hoped, but not surprising for some not-stunning photos on a lazy Sunday...
I guess I'll wait before I post the "answers" in case anyone else wants to play...
Further guesses by email:
YELM (well, MELM) preferred the night one but guessed that I "prefer the more industrial look of the first shot." FoSO didn't like either of them and had no idea which one I preferred, but did like the photo of the consulate.
