I'm still digging into the libraries of both, but so far, I've had way more fun with the 3DS library than the DS. It seems like the DS had a large quantity of great games, but the 3DS's smaller library has more amazing games. So 3DS quality > DS quantity for me.
I agree with those that say it'll be a more fair comparison at the end of the 3DS lifespan, though. Maybe someone will resurrect this thread at that time.
It'll be awhile before I figure out how to do one of these. :P
