I'd have to say "12" for a number of reasons. The sound is much more allowing for the subtleties of the song to come through on Brave Murder Day. But the most significant reasons why "12" is better is that they slow down the final sorrowful riff in the closing moments of the song, which creates a much more dramatic and darker ambience. The moments when the song pauses for the slow and haunting clean guitar breaks are also without any bass or keyboard in the background which makes these moments much more effective in creating an atmosphere of total isolation. Plus, Mikael's vocals are more powerful and emotional on the song than Jonas's on "Black Erotica", and I say that whil holding true to my stance on Jonas being my favorite singer of all time. But on this track, Mikael emerges the victor.
