Now that Pokemon is moving on on to the big screen, which handheld do you believe had the better lineup? Just as a refresher, not counting virtual console, backwards compatibility, or spinoffs:

DS
Diamond, Pearl, and Platinum
Heart Gold and Soul Silver
Black and White
Black 2 and White 2

3DS
X and Y
Omega Ruby and Alpha Sapphire
Sun and Moon
Ultra Sun and Ultra Moon

I'd have to give it to the DS
