While SDOIT has more replayability and wider range of ideas, SFAM trumps it as a complete package, has better flow and hits me in a more emotionally resonant way.
If I had to change one thing about SDOIT, it would be to spread the heaviness of TGP throughout the album. You have this crunchy, all-out metal bombardment to start the album, but is never followed through with another metal moment. Not saying TGP is the best on the album, but the energy of that song is unmatched by the rest of the album. SFAM, on the other hand, spreads out the riffage more evenly and is better paced.
Plus, SDOIT has Blind Faith, the one standout "average by DT's standard" track among the greatness of Disc 1.
