ITPoE.
I still like TCOT, but it hasn't aged all that well. These two songs share an interesting common feature: They both have this odd moment in the middle of the song where they are going full-steam and then come grinding to a halt with a slow, atmospheric section that takes the song into slow-buildup mode. The main difference is this: In TCOT, the interlude, while cool, is so long and drawn out that I lose interest and feel it kills the momentum of the song (not to mention that I've heard better volume swell effects from other guitarists). In ITPoE, the interlude is relatively short and immediately starts building into one of the best sections of the whole song (see TAC's post). So I think I have to give it to ITPoE.
