I haven't had to replace any controllers this gen, so I can't vote. They've been fine. I will say that my DS4s have horrendous battery life now, but it was never good to begin with.
edit: thinking about it more, and I can't even remember the last time I had to replace a controller. 360 controllers were solid (but I had three consoles fail), Gamecube, PS2, Dreamcast, N64, PS1, all of them were reliable for me. An Amiga joystick broke, but they weren't first-party.
