Topic: Which GBA Castlevania game should I start with?

I recently bought the Castlevania Advance Collection on my Switch Lite.

Prior to buying said collection, I played Super Metroid on my New 3DS XL and Switch Lite and liked it especially because of the upgrades (one of my favorite parts about Metroid games, especially Super), and due to that, I decided that I should try out the GBA Castlevania games. Those are Metroidvanias, right?

Which one should I start with first?

Off-topic, but I may edit the first post a couple of times.

@jrt87 I did the same thing at roughly the same time....and I even feel the same way lol. Circle of the Moon has fussy inputs but is pretty good, Harmony is ho-hum, and Aria onward is great.

Harmony is the easiest and most standard of the 3, and thus is the correct starting choice imo.

Quick question, I'm playing one of the games right and I notice an "?" symbol on the right side of the screen? Is there a meaning to it?

EDIT: Nevermind, I got the meaning of it. I assume it shows the item you collected.
