buy the system that needs your support to keep up competition
Ps4 or Wii U?
buy Wii U as there is a lot demand for the vita but not for wii u
3ds or vita
buy vita(same reason as for wii u
If you are just interessted in gaming?
You will miss Nintendoexclusives like zelda,mario,pokemon on vita
but you will miss fps on 3ds(no fps games there)and the shooter genre is a lot better to be played with 2 analog sticks and better graphics
than such good exclusives like hot shots golf,uc,gravity rush,tearaway
if you can't live without nintendo games=3ds
if you need more genre variety and better graphics & controls=vita
