Advice on new game consoles please?

I have some stuff to sell that may give me enough money to buy a PlayStation 3 or a PS Vita, and I want to know what I should buy. Each choice has it's own ups and downs so be sure to read the details.

On the Ps3 side of things, I want to play games like Resistance, Jak and Daxter, and TLOU. The thing is though, I already have an Xbox 360 and I only want a PS3 to play those games (as well as play with other friends that have a PS3 but not a 360).

At the Vita side, I can play Minecraft, Borderlands, and plenty of indie games on the go. But the PS Vita doesn't have a lot to offer gamewise (not a lot of 1st party support). However I'm usually out in public or at school so having those games to play would be fun instead of being stuck with horrible phone games.

Added (1). So what would be best to get?

Get a PC.

Id say PS3 even though the Vita is pretty cool what about PS4?
