Persona 4 is probably the best handheld game ever.
Dragon's crown is also amazing, and muramasa...
I guess it really comes down to personal preference. I tend to like quirky artsy japanese games, so that's why I like Vita, but 3ds does have some powerhouse titles.
Of course, my library would tell the truth of the matter. I have 10 games for vita, and 2 for 3ds.
