It's my favourite Castlevania on GBA and my second favourite Castlevania game after Symphony of the Night.

Game was a huge improvement over Harmony of Dissonance, and was probably the game that came closest to recapturing the feel of Symphony of the Night. Still, I enjoyed Order of Ecclesia more for at least trying to do it's own thing, and it is plagued by poor level design and the soul system lead to a lot of grinding. Okay game over all.

Good review. I consider Aria of Sorrow to be the best Castlevania game, slightly edging out SOTN.

probably the castlevania that I like the most from the ones that use the metroidvania style but my favorite overall still is the legendary castlevania 3 :), and is it wrong that I like the "worst" ending more than the others? lol

Nope.  The ending is awesome.
