It is still the best controller I've used despite having come from a console background so dual joystick controllers being my most used controller prior to it. I loved being freed of the reliance on aim assists and weapon/item wheels.
It's probably more due to not knowing how to use it and just going with whatever random config was applied. It's not a controller for people who aren't used to controller remappers and just wanted it to function like a xbox controller.
Long time PC and console gamer. For me, the X-box controller achieved the pinnacle of usability, I was intrigued by the Steam controller, but it was so shoddy.
