I liked both GS2 and GS1 soundtracks, though I think I enjoyed AA's music a little better personally.
For instance, I liked GS1's "Objection" theme alot more.

IMO, having listened to the various soundtracks:

Courtroom Themes: GS1 > GS2 > GS3

Testimony/Cross examine themes: GS1>GS3>GS2

Cornered Themes: GS1 (Like we expected any other?) > GS3 > GS2. I can't wait to see how the redo GS3's cornered music.

Phoenix Themes: GS3 > GS2 > GS1

Ending Themes: GS2 > GS1 > GS3

I don't know if you can compare GS4 in the same category as it is completely different in composition and feel, but the examination music and Odoroki's theme are godly. The cornered music makes me cringe like nails on a chalkboard.

Magical Track Society needs to do more remixes of GS2/3 music. Imagine a remix of GS3's cornered theme done by them in the same style they did GS1's theme.
