For me, the controller is a no-brainer. The question I ask is "Does it give me hand cramps after prolonged play?" And the PS4 as with every other PS system does not fail to disappoint. 4 hours into Killzone: Shadowfall and I get the old familiar tingle followed by increasing pain in my index finger on my right hand and my ring and pinky on the left. While it must be said, I have carpal and cubital tunnel syndrome in my hands respectively, the PS controllers have never felt comfortable to me. It may be they their target market has smaller hands, but those things feel like a child's controller in my hands. The bumper and trigger buttons are still too close together and the trigger still doesn't extend down far enough. Did Sony just not listen the complaints made about the Dual Shock 3 controllers? I end up with a gaming claw after a few hours. Not as bad as the Gamecube mind you (oh God, the pain), but the XBOX has consistently beat the PS as far as making an ergonomic controller, at least in my opinion. It got so bad on the PS3 that I ended up buying a Power A controller because it mimicked the size and shape of the 360 controller. Loos like I'll have to do it again.
As an aside, I did *not* find the setup on PS4 to be a breeze. I had some issues with my router and the PS4 that took me about a half an hour to fix. That said, the new UI is waaaay more intuitive than the PS3. If I'm being honest, it reminds me of the 360 though, which I much preferred to the PS3, but full marks to Sony for making that improvement.
I don't have an XB1 yet so I have nothing to compare it to, but what I've seen doesn't strike me as all that different from the 360. Not sure if that's a good or bad thing... but hopefully the controller is big enough for my "manglers".
