I like "Dragon spirit", check this video which including the 1st stage BGM from NES, PCE, and AC versions. I think PCE version is awesome! Especially for the high, crystal clear tone.
Make more comparisons like this
Whilst I love the arcade version of Dragon Spirit, I feel that the PCE tunes are the sweetest: the PCE, with the subdued drums, places emphasis on the wonderfully warm, smooth, layered "synths"--a very "full" sound. Cozy. Comforting. I love it.
The arcade, while featuring a nice arrangement, has a significantly
less lush sound and the overall mood is somewhat cold... the arcade is not as endearing as the PCE version.
Or in other words:
PCE = HubbaBubba
Arcade = Bazooka (flavored!)
FC = DubbleBubble
