I usually prefer the PS3 controller, but went 360 pad for my PC. The native support in many games is very nice and I wasn't willing to deal with any possible headaches of getting a DS3 recognized ...

All-in-all, the DualShock 4 is a great controller for your PC with just a few caveats. It would appear that Windows users have it easier than Mac gamers, but that is somewhat to be expected.
