Unless I am misunderstanding, the OP is going to buy BOTH consoles but wants to get one this year?
That shouldn't be a contest. Shooters, retro platformers remade and Tomb Raider are all landing on Xbox One this year.
Get that now, and the PS4 next year when most of its currently hyped games are due to land.
