It's easily the best controller I ever owned, not counting K+M combo of course. The size, shape, button layout, trigger feel and response, and the simple look and finish are 100% brilliance. The weight is also perfect; not too light and not too heavy. Xbox controllers have only gotten worse since Xbox 360, which had amazing controllers (the Nintendo Pro reminds me a lot of these in shape and heft). PS controllers have been mostly okay, but nothing more, the DS4 was a huge letdown, with the annoying touchpad and the useless lights that ate battery time, the DS3 was way too heavy and too small for my hands. I've yet to buy a PS5, so I have no opinion on the controller, but I've heard mostly good things.
Oddly enough, the worst of the bunch is Nintendo though, their main controllers for three consoles in a row have been absolutely horrible for me. Not to mention the insane pricing (I remember when Wii-mote + Nunchuck set you back around 130$ here) and technical issues with them. But, the Pro controller makes up for all of it. I hope it'll be fully compatible with their next console as well! I tried making mine work on Windows 11, but gave up and am now using a standard Xbox One controller instead.
