Have all 3 consoles.
PS4. All multiplats I play on this. There have been a good amount of exclusives that I've been interested in and played as well. I vastly prefer the ps4 controller over the other two. And I like the ecosystem (the store design, history of purchases, webstore in general is far better on PSN than the other ones). Most of my friends have the system as well so we can borrow games off each other, bring a controller over etc.
My next most played system would be Wii U due to local multiplayer games like Mario Kart and Smash.
Then Xbox One for some exclusives. If the Xbox One was more portable/had no power brick, maybe this would get more play as EA access is available on it and I'd subscribe in a heartbeat (damn you Sony!), but it's too much of a hassle to move it from my basement to my room, or to have it be a permanent console in my room due to how big it is.
Currently what my setup is that I have a power cable, hdmi and LAN cable on standby in my room and the basement, and have the ps4 connected in my room for most of the week, and take it back down to the basement on weekends if friends are coming over and we want to play some COD splitscreen or Rocket League. So the only thing I'm really moving is the console itself, the cables stay where they are. Takes less than 20 seconds to connect back up.
