Yeah, whatever the newest album is when a poll like this is done has a bit of an unfair advantage. That's just the way these things go.
I think I would probably put them like this:
1. Six Degrees
3. ADTOE - I still love it, and I am still blown away that, so late in a band's career, they could put out something so consistently incredible from start to finish.
4. DT12 - Picked up right where ADTOE left off. Perhaps even MORE consistent than ADTOE, but the highs just don't reach quite as high for me.
7. The Astonishing - I finally feel like I can rank this one. Right now, I definitely listen to it more than any of the albums I rank ahead of it. And I love it right now more than I did at release time. But it has settled in enough that I realistically feel the six albums I rank ahead of it are just a tad stronger and that I enjoy them a tad bit more.
8. Octavarium (nugget!)
9. SC - On the strength of ITPOE, Forsaken, Constant Motion, and TDEN, this album gets a nod over one of the classics. I might put it over Octavarium some days as well.
12. Black Clouds
So, yeah, TA at #3 of the RR era for me.
