HS and SS over Black and White any day.
I love my non moving sprites, my old exp system, my Bro's following me and and my non generation V pokemon (They're all ugly and/or whack). When I play White and then go back to SS I can't help but feel disapointed by White, storyline, pokemon, battling, all just seem inferior to Generation IV. I actually hate black and white, they're my least favourite games in the series, should probably get some money back for it.. I've restarted SS so many times just for the thrill of the story. B&W's is stupid, saving the world is totes not what I do in every other game.
Maybe I'm extremely conservative.
Hopefully (to me anyway) they change it back to the old system in the next games, otherwise I'm a be a sad gangster, and hoes will be slapped. With both hands.
