That seems to be the general theme I've seen here in the thread:Capitano Segnaposto said:They are both equally great.
3DS has a ton of games that you can play now and a ton of ones that will release shortly. The games are all fun and different.
Vita has very little games. So far 90% of my library has been from Japan via Imports. The Vita needs some games, badly in the States. However, other than that I do love the lack of a region-lock and the games that I have played for it were a lot of fun.
The 3DS right now has a ton of games and the Vita has a ton of potential (or a ton of games if you speak Japanese...which I don't). At the rate it's going, it's likely I will go with the 3DS and keep an eye on the Vita (especially for this rumored price cut coming this year).
However, that PS+ service though (especially in combo with my PS3) sounds like a Vita's dream. It's the wild card forcing me to keep my bets in check and not just declaring the 3DS the winner. Also, getting PS1 and PS2 games onto the Vita with the download service alone kind of makes up for the lack of Vita specific hardware. There are an awful lot of games for the older generation I never got to play (Persona 3 to be specific but I'm sure there are plenty of others).
*Sigh...why can't I just have the money to buy both! That's make this way easier to decide
