Good job on that one Screencap, Paul.
Other than that, I think the one Castlevania that the PCE got was just as good as it can get.
Super Castlevania, Bloodlines, Symphony, Rondo and Rebirth seem to me be perfect matches for each console hardware they've been released on. Super wouldn't be the same without the silly Mode 7 shenanigans and the farting SPC trumpets. Bloodlines pulls some graphical tricks out of the then aging Genesis you wouldn't expect from it. Symphony is a great amalgamation of smooth animation, rotation/scaling effects and a good soundtrack. Rebirth's fantastic Arcade Konami style synth music would be pretty hard to replicate faithfully on 90s console hardware without going for redbook audio. And talking of Rondo, you guys all know well enough how it turned out when being ported to the SNES.
