Game with Controllers

I personally think controllers are not really useful. I have over 1k hours in all of From Software games on PC and never experienced any issues while paying keyboard and mouse, but when I tried playing BloodBorne on my friend's ps4 it was kinda harder to control my character. Controlling camera on a gamepad is very frustrating for me. Though i had a hard time evenwhen I triedplaying SMB on his console, so maybe it is just that i'm not accustomed to controllers.
