I bought a Razer Raiju today, for my PS4. I wanted a controller with paddles and I feel that Scuff are pretty tacky, so it seemed like a good bet.
So far so good. Controller feels great to hold and use, incredibly responsive, feels a little nicer to aim than with the PS4 controller, not sure why, but I immediately felt the desire to turn the sensitivity up on this one and felt a lot more accurate at speed. I would say it's because the control sticks are elevated but that's not the case compared to my DS4, since I was using Kontrol Freaks anyway.
Shifting to paddles from the 'Evolved layout' is tough. My muscle memory is still telling me to press R3, which is causing me to melee. Ultimately this might take some time to adjust. I've been using the Dual Shock in one form or another for 15 or so years.
