wii u pro controller for me.
I just have the wii u gamepad, wii u pro controller and the dualshock 4. I played some with xbox one controller by a friend though.
I do prefer the wii u pro controller with 80 hrs battery life. The l2/r2 buttons (digital) are alot more comfortable then the analog triggers on dualshock 4 (i dont play racing sims).
So overall yeah wii u pro controller, but havent use the xbox one controller as much so cant say enough about it.
