I voted TA, because I think it's the best RR album as a whole, but the last 3 albums (ADTOE, DT and TA) are, to me, much better than all the other DT albums after SDOIT.
I rank them:
- TA
- ADTOE or DT12
- DT12 or ADTOE
- SC
- BC&SL
I should say that I love SC and rank it higher than most other albums, just find the MM era albums much better. About Black Clouds, I used to like it more, but now I think it's one of the worst DT albums. TCOT is reaaaaally good, though.
