I'm sure you will enjoy it. Coming from one that owns both Vita and 3DS, I found myself playing 3DS more than Vita with games such as (in the order of preference): Brain Age (one of the main reason why I procure a 3DS in the first place), Etrian Odyssey, Phoenix Wright series, Professor Layton series, Animal Crossing, Tomodachi Life, Super Mario 3D Land, and Harvest Moon (sadly I still think HM: Back to Nature for PS2 is the best). In comparison, I only played Gravity Rush, Disgaea, Final Fantasy X and X-2, Metal Gear Solid. Although enjoyable, these games don't really have much replay value and is sealed in the closet once I beated those.
A bit of sidetracking there

In my personal view, I found that Pokemon series had gone through significant changes ever since Black with the increasing complexity which I don't have much time to enjoy. Don't get me wrong though, the game mechanics itself is surely attractive for veteran players but for me that often juggle between games and with limited play time, I got to make sure I distribute the time spent on every game possible. Frankly, I can't recall the storyline for Black/Black2 and X/Y few months after I beat it. But I can perfectly recall Blue, Crystal, Emerald, Platinum very well enough. I must have been too old for new games XD
Who knows, I might start to enjoy Pokemon again when Omega Ruby is released since I really enjoy the game much. Hope they don't introduce any new elements on that game other than touching up the graphics that might spoil the originality of the game. The good old days when I play Ruby on my silverish GBA with dozens of battery replacement. You got to make every second counts to maximize the battery efficiency.
