3ds vs playstation Vita

ok i have the DS in all verisions (yeah a nintendo junkie !!) but now looking into VITA, anyone have it? and what do u think is the better system, when i discussed this is on the PS network forums got told the DS has the better libaray, but the Vita is a better all over system... whats ur opinion?

I know this may be a late response, but stick with the DS. It's much more fun, and the Vita just doesn't feel right in the hands.
