I have both since their respective launches, and, so far, I prefer the 3DS. I have about 15 games for each system (not including backward compatibility). For the Vita, I've bought plenty of games that I really expected to love (Disgaea 3, Uncharted : GA, Gravity Rush, AC:Liberty, Escape plan, LBP:Vita and Unit 13 to name a few) but only enjoyed a handful of games (Zero escape, Persona 4, Dynasty Warriors Next and Lumines). On the other hand, I bought the 3DS not expecting many good games other than the usual Pokemon games, but was happily surprised by Fire Emblem, Project X zone and SMT4.

I think both systems have their fair share of good games, and while the PSVita is more powerful than the 3DS, the 3DS is still a very capable handheld able to deliver great games with decent graphics. Like I said, so far I've played more on my 3DS, but this generation is still young and the PSVita line-up seems solid, and I'm pretty sure that both systems will deliver a solid experience in the end.

I recently sold my 3Ds because I was very unhappy with the outsourcing of games Nintendo has been doing in their right now Best selling system.

What made me sell it? Donkey kong 3Ds...

WHAT A TERRIBLE piece of crap port...not only were the graphics subpar and blury in some cases, the game ran 30 fps or less....the 3DS should have NO problem playign this game at 60 fps...most mario games NEED to run 60 fps because of the input latency...Why on earth did we get such a crap port? The Wii one is 100x's better just because it's double in frames (trust me, if u are a long time platformer fan you'll understand my plight).

Mario 3D was far better and personal A LOT more enjoyable...I actually played that game for 90+ hours! Another amazing game that would make me rebuy the system is Fire Emblem <3 that game!

Anyways for now I'll stick with Vita only because the 3Ds is only going to get cheaper and I can wait until the next mario/Super smash game/Zelda to get it (actually hoping for Zelda Limited edition bundle:D).

Anyways, my vita I love the convenience of having 8+ games on my 32 GB card, and I'm a huge fan of the actual asethetics of the console, my hands feel more comfortable with it, the 3Ds felt cramped and the 3Ds Xl the screen pixels anger me...

ANyways

I do agree that the 3Ds has better games over all, but it's graphics doesn't come near to compare with the vita (at least for 3rd party games)...but most Nintendo games have such simplistic graphics where it really doesn't matter, it can look next gen by making minor tweaks:P.

Either it would be nice for people to own both, for now I have a butt tone of Vita games I need to finish (I couldn't finish em cuz I was playing too much Fire emblem lol!)

COD (I want to platinum it...its not as bad a game as ppl say but its def not a good Cod game..a lot of glitches)
Persona 4 (plat), mickey ( just fun:P), Jack and daxter, steath Asshole, and WRC3:)

PS Vita is more powerful than 3DS, very powerful for a handheld(see Killzone Mercenary), but Sony is not marketing it well, I don't see any ads about it(except in Japan), they are acting like they given up on PS Vita, and the second thing isn't about lack of games, it has many games, just not enough good games that people prefer and lack of exclusive to make people buy one.
Sony just needs to market the Vita better, but i have a feeling Gamescom should show some new good Vita games, hopefully.

Just proves power is not everything, the 3DS just has flat out better, more fun games.

As far as handhelds go it is my choice of system.

Got to love all the disagrees from Sony fanboys who can't hanfle the fact the Vita does not have a library worth buying into

Oh lovely flamebait N4G.

3ds all day every day. Vita has good hardware but no games. The only standout is Persona 4 which is a port. I can't name one other game that's as good as Fire Emblem, RE, Kid Icarus, SMT4, Kingdom Hearts DDD, Devil Survivor, Etrian Odyssey, MH Tri-g, Code of Princess, MK7 exc. the only upcoming games are KZ, Dragons Crown and FFX, one of which is a port. 3ds has a sequel to Zelda ALTTP, Mario and Luigi Dream Team, Pokemon, Etrian Odyssey 5, MH4, Dragon Quest 7 remake, Bravely Default and a dozen others. There's no compitition at all and the fault is sony's. They need to make high quality game and a lot of them to sell systems. Once systems sell other devs will jump on. Sony's waiting for sales to make games for their own damn system!

I prefer the 3DS simply because it has the types of games I want on a portable console. I've owned Nintendo handhelds for a long time, and I've been happy with all of them. This isn't a knock on Vita, this is me saying Nintendo offers what I prefer.

However, that won't stop me from eventually getting a Vita. Especially when I'm going to be owning a PS4. Plus, Tearaway looks great.

Like someone said above, so much of this debate is entirely subjective. Go with what feels right for you. Also, there's nothing wrong with owning both of them if you can afford it. Both offer almost completely different experiences, and can coexist very well. I've said it so many times, but this portable console war is absolutely pointless.

I've had a 3DS for years but I've also seriously considered a Vita. Its so pretty. But, it doesn't have any of the games I want or would find enjoyable.

Sony markets well to only four sets of gamers: guns, fighting, racing, and sports (marginally). If you don't like any of those things, you're stuck with Little Big Planet, and that isn't enough to carry a system.

If Sony diversified its catalogues, I would buy its products. But they don't, so I won't.
