I voted Aria and Circle.
Symphony would have only gotten the points on graphics, animation and one or two gameplay mechanics but overall it wasn't as good as it was hyped to be.
Long dull coridoors, interestng weapons that were far outclassed by the time you got to use them and so never bothered and toooo easy.
Aria gets it right on everything, even graphics considering its a GBA title, imagine it with SotN graphics.
Circle gets my vote also because even though it's mostly whips the weapons were variable, there was a deffinate oldschool castlevania difficulty about it and the art style was gothic just as it should be for CV
