I've never had an offical GameCube controller before, but my impressions of this controller are not good.
With the product I got, the L and R buttons are way too stiff, you have to put a lot of pressure to actually press the buttons down. The rest of the buttons are slightly stiff as well. The sticks also came stiff to me but at least it's better to have stiff sticks than loose sticks in my opinion.
But those are just minor complaints. The biggest issue about this controller is that the control stick only moves in 8 directions. This is a huge issue with platformer or movement-heavy games. I'm not sure if it's just my Wii console, but at this point you'd do just as well to find some way to stick a keyboard and mouse into the console and just use WASD. This was one of the reasons I bought this controller: to have better control over movement than using WASD on a keyboard with emulation. Just buy the official controller instead.
