G/S/C
I'm gonna be honest.. I never beat any of the original gen 2 games, and I stopped watching the anime during gen 2, as well (Got back into with gen 3). I didn't hardly care for Johto at all until the remakes came out, and even then.. I've got Heart Gold sitting there in my room unfinished. I have no idea what it is, or the reason for it, as to why I can't get through a Johto game. It baffles me, they just don't grip me, yet all the other gens have. /shrug The remakes still beat out the original by a long shot, though.
FR/LG
These I liked just fine, and I've played LG twice, and enjoyed them just as much as I liked the original three games. There's not much to say about them past that, but yeah. I like the remakes more than the original, because it's same freakin' thing just prettier, that's my logic right there.

The remakes are better. xD
