Anyone who actually picked a side is wrong.
If you truly are a fan of JRPGs both of these handhelds are a must own.
PSVita has PS1, PSP and the Vita's JRPGs which often are more niche however there is the occasional large title.
3DS has DS and the 3DS JRPGs which are often more well known like Dragon Quest or Kingdom Hearts.
Both however have too many amazing games stuck in Japan, so you best start learning Japanese now.
