Oh yeah, I've played them all, loved AoS.
In order of favorite handheld Castlevanias my list goes something like this:
Order of Ecclesia: Loved the village, loved the little sidequests, loved the difficulty, loved the souls and weapons systems... just loved everything. Perfect art, great little story, and probably my favorite OST of all the handheld games.
Circle of the Moon: The first GBA one, this one needed time to grow on me. But in retrospect, it's one of my favorite to keep returning to. It's incredibly hard and a bit clunky, but there's something about it, between the world design, the card system, and the ominous tone that continues to grab me.
Aria of Sorrow: The first to really feel like SOTN, bright, colorful, with incredible animation and music. In fact I loved it so much I felt pretty let down by the sequel (Dawn.)
Portrait of Ruin: I really liked the world in PoR.. something sort of NES-era Strider about it. I mean, how often do 2D games take you to egypt these days? I also thought it did a great job with having an AI partner.
Dawn of Sorrow: I know many list this one as their favorite, but for some reason it never grabbed me. I hated the antagonists for the most part, and something about it always bugged me. But the near-future setting of parts of the castle were cool.
Harmony of Dissonance: I actually really like this Castlevania, and thought the dual-world concept was neat, if a bit confusing. But dat animation.. oye. And Castlevania has always been at the forefront of awesome when it comes to music. Not this game. Some real ugly level art here and there too.
Mirror of Fate: I'm too early in to say much, but so far it's making me very sad.
I'm catching up on all the GBA games since I commute everyday.
Playing through Mario & Luigi:SS now
Got Circle of the Moon and the Metroids up next.
Then I'll probably switch to DS for Order and Dawn.
Metroidvanias are just too good.
