This comparison is off.Yes the Vita is much more powerful than 3DS. Vita isn't far behind PS3 on many levels. 3DS is Gamecube and Wii sorta with better shaders and other advances. But still a long ways back from Vita. That Xenoblade screen is no doubt the Wii version. Not even worth doing a Screenshot battle. This isn't VGC and it's pointless lets compare PC games to consoles then.
For the record Vita GPU is the same from Ipad 3. 3ds Uses Pica 200 a GPU from from 2005 tweaked. yes 2005.
Personally I think the Vita just is a better more thought out system and I don't mean because power alone. The system is immensely easier to and cheaper to develop for than even PSP. Yes PSP. Despite more power. Sony set it up that way to be more open to developers. Falcom confirmed it when Vita was still called NGP. Has a nicer UI and can custom backgrounds and themes more so than 3DS. Nicer to use hold and play.
Nintendo kinda sucks at console UI. At least to me. Wii,Wii U and 3DS esp DS. Not used a PS4 yet but Sony is prety good. MS is the worst which is odd.
3DS is just not the DS in terms of variety in games and region locked holds it back a lot for me. Vita is region free. 3DS still from a volume of games has more to choose from and of course Nintendo first party but some none mario/zelda greatness like Fire Emblem. Some 3rd party greatness as well like SMT or Code of Princess. There is a whole lot more. 3DS has more to choose from. I just don't think it has enough for such a successful system. Like no real hidden gems for me. A few scattered interesting 3rd party games and then Kirby/Mario/Zelda and that's kinda sad. Vita has much less to choose from but that is int he west. While my bias for Dragon's Crown and Ys would make Vita a default winner and more Ys this year. Vita being region free has a lot of cool games from Japan. A lot of that Japan hidden gem and quirky to just great games and RPGs. Visual novels. Action games and more. Like you can get a Tenchu like game on Vita or Okami like visuals RPG Oreshika.
Sadly yes not in the US strictly but in Japan Vita has far more to offer in variety. Just Sony of the west gave up. Vita will say again is region free can just buy those games. I am still hoping for DQ7 but gave up on Labrynth on 3DS coming to the US. 3DS is a more popular system. better marketed and more popular franchises. Vita has crossplay. Nintendo just now opening up to it.
E-Shop is decent on 3DS while Vita offers again much more. Nintendo also seems to think 3DS can only handle NES games or Gameboy. I can buy Legend of Dragoon or Klonoa on Vita and play it on PS3.
I truly feel Vita IS the better system all around. 3DS is more popular as it has the brand the marketing and more familiar faces. Popularity does not mean better. Much like Wii U is better than PS4.
