I'm one who doesn't care about sales and how many games a system has. But it's the quality of games that matter.
The only game the 3DS has coming out that I think is worth purchasing is Code of Princess. There's also Rayman Origins and Sonic All Star Racing, but it's a port and a multiconsole title, something people either own already or are going to own on another console.
The Vita has only been getting a few releases, but a lot of these releases have been quality. While that quality is mostly contained to first party titles like Wipeout 2048, Unit 13, Gravity Rush, and LBP2, it's still quality nonetheless(there are some good third party titles though.) The Vita's first year is finally coming to a close, although that's only in Japan, still another few months in other areas,) and this is where the flood gates have been unhinged. Or maybe flood gates is too much. Whatever. The Vita is getting some good games these next couple months.
As someone who owns both the Vita and 3DS, I've felt my 3DS has mostly been a waste of money. The few exclusives that have came from Nintendo as first party haven't been as good as what you'd expect would come from them. Super Mario Land 3D and New Super Mario Bros 2 were both disappointments, and Mario Kart 7 was a great game outside of the fact that I've started to get bored of the series because I quit playing it in less than a week. The only other games have been third party titles and there hasn't been much of an offering there aside from games I already own on another system, games that are actually mini games on games I own on another system, or Resident Evil Revelations. Heroes of Ruin is good, but way too short.
The 3DS and Vita really seem to be following what has happened with the DS and PSP. The PSP got less games, but more qualitiy titles, while the DS got more games, less quality titles. However, I think overall, the PSP and DS both ended with around the same amount of worthwhile games and the same is probably going to happen this gen with the 3DS and Vita.
