Got mine today and I'm not sold on it yet. It's more hideous in person than in pictures. The texture on the back is more abrasive than the DS4, almost like a nail file, yet it's more slippery than the DS4 and provides less grip. It seems less comfortable to hold. The grips are too thick that it makes it hard for my right hand to get a comfortable placement to interact with R1,R2, face buttons, and right stick. As I hold it my pinkies grip half-way off the bottom inner edge, which at least isn't sharp but it's still an edge and its not comfy at all compared to the rounded edges of the DS4. Even the bottom outer edge of the grips push into my palms some. I was worried about these plate looking things on the controller since first seeing them and it turned out just like I had imagined. I really don't understand the choice to add hard edges to the design. There is one sharp spot on mine on the inside of the grip below the right stick, but I don't really hold it there except for with one hand off the controller and I can always sand it down with the texture on the back of my 2nd controller when that arrives. The buttons all feel good, nothing too noisy or anything. Only the d-pad is slightly too sticky of a surface and hard to slide my thumb across it, actually making a squeaky noise on the surface.
This is before playing any games with it of course. Maybe the roughness won't be so noticeable while playing. For now it's bring back painful hand memories of the Dreamcast controller, not even close to as bad though. The adaptive triggers and other features might make up for the loss in comfort once I can test that out.
