I actually play with a dualshock on PC. A keyboard is fine for me until I'm dealing with 30 different buttons to push. The keys all feel alike so the further I have to reach with my fingers in the heat of the moment, the more likely I am to hit the wrong key. The dualshock however feels good when properly configured with the R1 -> R2 / R2 -> R1 setup. The only thing I don't like about it is target swapping on aoe.
