#10 for me, ahead of ADTOE and WDADU. If IT weren't dragged down by the orchestral section, the album might move up one more spot (beating out 8V for #9), but alas. In some ways DT12 is the most consistent album they've had since SFAM--nothing on it inspires active dislike from me, except maybe that AFTR sounds like it was written in ten minutes--but there's an almost complete lack of real impact moments for me. Except for the post-orchestra part of IT, the strongest reaction I have to anything on the album is "that's a pretty good song."
Also, on the how-does-it-compare-to-other-music debate: The flipside of the "running out of ideas" on a twelfth album is that, by album #12, a band should know what they're doing and turn out professional-sounding, consistent records (like this one) in their sleep. Bands earlier in their careers may have more ideas and energy but struggle to harness it (ala WDADU). Also, on the subject of 2013 progpower releases that are way above DT12, Delta's The End of Philosophy tops that list for me.
