Alright let's give it a shot
1. Awake - Most balanced, consistent, dynamically diverse, emotionally packed, and atmospheric album.
2. Six Degrees Of Inner Turbulence - Most diverse album in general, every song is intense and charged with emotion or badassery.
3. Metropolis Pt. 2: Scenes From A Memory - Perfection of melodies and composition, also has one of my favorite album beginnings and endings.
4. Images And Words - Most natural and original songwriting, every track has its own beauty.
5. A Dramatic Turn Of Events - Return to form that has some high highs and okay lows, instrumental composition is very good.
6. Dream Theater - Very dynamic and focused, short and sweet, but doesn't give much to dissect or reward a ton of listens.
7. Train Of Thought - Just an extremely cool and badass album with every track, but a little unbalanced as the constant heaviness can be fatiguing.
8. Octavarium - Amazing title track, but the rest is fairly average. I do like the atmosphere though.
9. Black Clouds And Silver Linings - Epic and dynamic but tiring to listen to as a whole, most tracks are good individual listens.
10. Systematic Chaos - Same as BC&SL, but with more throwaway tracks.
11. Falling Into Infinity - Most of the songs sound like b-sides in the way they're written and composed, only a few individual great moments.
12. When Day And Dream Unite - The songwriting is all over the place save a couple good melodies, it doesn't really invoke anything musically for me, even if the production were better
