DS4, by far.

Dualshock 4, but even that one is bad compared to X1's controller which is the best controller ever made imo.

The latest DS4 is by far my favourite PS controller. The ergonomics of the previous controllers just didn't agree with me. I thought prior to DS4 the controllers were just too small, uncomfortable and the buttons would give me blisters after extensive gaming sessions like Tekken. The DS4 fixed all those issues. My only remaining issues with the DS4 is the battery life is quite poor and the analogue sticks wear off far too easily (I've had to replace mine with XB1 sticks).

DS4. The extra weight and changes in ergonomics makes it best.

It can only be the original dualshock in my opinion. It was so comfortable and looked great. And was the only playstation controller that really changed anything compared to the predecessor. The second dualshock was almost just copying the first one. Sixaxis and Dualshock 3 had those gimmicky motion controls.
I don't like Dualshock 4 at all. Ogly, low battery life, poor quality of analogue sticks

The original PS controler is still king for what it was made for, early PS titles and aracde games. It works much better for fighting games than any DS until PS4

The only one to not crap out on me halfway though a generation - Dualshock

(Granted I don't have a PS4 but a cousin and a friend's DS4 have already shit the bed for both of them since launch)

Definitely the DS4. All the improvements make it damn near perfect. Should have put a larger battery in it, though. Hopefully, they fix that with the Neo's controller.

The DS4 easy. My favorite controller period actually. Followed by the 360, and Gamecube controllers.

I actually think X1 controller is worse than the 360 controller :|

Dualshock 4 is by far the best PlayStation controller, and my personal favorite controller to date.
