The GameCube Controller

As if we could choose anything else. This is the best console controller in history. – David Trammell

There is nothing at all that feels better in your hand. Nothing. Period. Ever. – Billy Berghammer

You’ll get no argument from me: the GameCube controller is where it is at. It’s so small, comfortable and well designed. I can play for hours and suffer far less wear & tear on my hands than ever before. It feels so right in your hands, sometimes you won’t even know it’s there. – Max Lake

Best controller since the SFC. - Zosha Arushan

the GameCube controller is easily the most comfortable, offers new possibilities in the Trigger ‘Click’, and just flat out rocks. – Mike Orlando

Yummy is the best way to describe this controller. It's super comfortable and very well designed. – Mike Sklens

This controller is simply tough to beat. It melts into your hands. – Mike Hrusecky

It may be a little small for the minority, but with the possible exception of the Z-button the whole product is comfortable and intuitive. – Michael Cole

I held it for the first time in November, yet it felt like I had held it

for a lifetime. – Jeff Shirley

I don't buy that it's the best controllar evar!!1 slobbar, but it's still absolutely fabulous. Why even have this category? I mean, really? – Ty Shughart

Nintendo again raises the bar and provokes third-parties to copy a wonderful design in ergonomics and control. More importantly, the "click-action" of the shoulder buttons opens a wide-variety of control options for developers! – Rick Powers

Melts in your hands. Also, considering there aren't many other first-party accessories out there at the moment, this is sort of a no-brainer. – Steven Rodriguez
