The NES games definitely for me. I mean, technically, I've only played up through the PS1 games, and seen an LP of Order of Ecclessia (spelled wrong?), but I still like the NES games best. Symphony sure was fun, but there was a lot of running around and back tracking. Simon's Quest did the same thing, but Simon's Quest is a lot shorter of a game, it's meant to be played in one sitting, so it's not asking too much for you to run back 10 minutes to reach the third dungeon (although, it is still annoying.... really annoying). Then again, unless I'm playing an RPG, I only like Linear game play, so my opinion is biased (that's a bit redundant, don't you think?), so the NES games, specifically 1 and 3, are the funnest to me. Also, Castlevania 1 is the only one I played when I was really young, so it has a Nostalgia factor for me.
