I don't think we can make that decision for you, it'll depend on which library of games is more appealing to you. Do you like Pokemon or Persona? Zelda or Uncharted? Mario Kart or Wipeout?
I couldn't decide either, so I own both. They're not that expensive (compared to home consoles) anyway, and you can pick up both for less than a single PS4 or Xbox One.
Personally, I ended up playing the Vita more, probably because it's more like a normal console that you can take with you, and it has a good selection of PS1 and PSP games for it as well.
