This is speaking from experience, having played a PS3. The controllers have changed very little. The Xbox controllers sans the original have always been great.
Cause it's a design that's been tested since the first Dualshock controller released on the PS1, and it was phenomenal. This is speaking from experience, having played the PS1, PS2, and PS3, that having the gamepad and left thumbstick in the PlayStation configuration is way better than the Xbox configuration.
Anyways, just get a good PC. If you have to choose a console though, just get a PS4.
