I think ADTOE is amazing, but I'm not sure if I can say it's as good as the great albums albums Octavarium and Metropolis pt. 2 scenes from a memory. (my favourites). With that said I love the new album as well. I just think Dream Theater has so much epic and amazing music that it's probably hard to make something better.. (even for them).
