For those who have the PS4 controller, I currently use both PS3 and 360 controllers, and prefer the PS3 controller, because it doesnt require as much force, to press/activate a button.

(But this is only noticeable when u have carpal tunnel, and every single press of a button is ten times more noticeable because of the extra pain inflicted when u press down harder on a 360 controller.)

Most people (including myself originally) wont be able to tell, but if anyone here can, please let me know. (Same with the thumb sticks, as 360 sticks are harder to move, which I like for FPSs, but not anything else)
