Very hard to tell, I got every PB game so far, their port makes the game even better in portable mode. So it's mostly how I like those 4 game.
I really loved Wolfenstein II, I've spend nearly a week playing it all the time. But Rocket League is THE game to play with friends when you want to push the gaming night further than just the ride stuff on Super Mario Party. And also, Warframe is, I think, one of the best looking (if not the best looking) games of the platform, and I've spend a lot of time in it already.
Hard to tell. But since I didn't enjoy Doom as much as I tought (I spend nearly most of my time running away from deamons rather than chasing them), I'll say it's a tie between the 3 mentionned above.
