This was a tough one, but I went with The Whirlwind, mostly because I love pretty much whatever Neal releases, especially if it has Mike drumming on it. This was their come-back album, and I hope we get at least one or two more from them in the coming years, but this album has a LOT on it, and while that may turn off some fans, it's right up my alley. It's big, it's epic, it's got repeated themes, it's got some AWESOME musicianship (most notably Pete's bass playing, and his levels in the mix are just astounding!).
ADTOE is great, but it's still growing on me. It definitely wowed me the first time I heard it, but BMUBMD was a bit of a o.O moment for me, as was the intro to BITS, but it's got some awesome songs and sections, but with The Whirlwind, because of the nature of the album (being a concept album), I knew to get into it as a whole, so I absorbed it entirely, yet slowly. With an album like ADTOE, I absorbed individual songs at a time (mostly OTBOA at first, then the chunk of FFH/BAI/BTS, then LNF and Outcry, and finally BMUBMD and TITL), so it's become a bit uneven for me, in terms of enjoyment. By now, though, I've come to appreciate each song for what it is.
Just for fun...
Mix - Tie (The mix on both albums are top notch and I cannot fault either album in this aspect)
Lyrics - ADTOE (I love TW's lyrics, but ADTOE has some touching pieces, and features the triumphant return of JMX to lyric writing!)
Writing - TW (Considering the album was pieced together mostly by Neal and Roine, with bits from Pete, and in-studio jamming, it's amazing what came together in a week and how cohesive it all feels!)
Vocal Performance - TW (I love Neal's/Roine's vocals on TW, and I'm very happy to have heard lead vocals from Pete and Mike)
Guitar Performance - Tie (JP has some great stuff on ADTOE, but it's all very 'usual' to me, while Roine has some fantastic solos on TW)
Bass Performance - TW (Pete's levels and performance just take the cake, and TW might be the best bass guitar studio recording I've ever heard)
Keyboard Performance - ADTOE (No offense to Neal, who is an amazing player, but JR has some great skills and wasn't afraid to let it all out on the last album)
Drum Performance - ADTOE (although MP does some of his BEST drumming on TW, MM slightly edges out)
With two ties and a 3-3 match, it's pretty even, but I think because TW has been out longer and has had a LOT more time to digest, it's become a favorite that will take awhile to top. It's really close, and while Dream Theater are my 2nd favorite band, Transatlantic are not far behind, and it will take a lot for any future album to top something like The Whirlwind.
