Lets face it, over time the standard gaming controller has seen many iterations. But which is your favourite? For me, its the Gamecube controller. Why? Has to be THE most comfy, responsive and downright awesome gaming controller ive ever used. It has a simply layout, the shoulder buttons has those deep grooves so your fingers were literally always in them, the c stick was a sly addition, often used as a a camera operator or even in some cases item selector or to harness the power of your Wind Waker!
While each gaming controller is special in its own way, and most every one has a special place in my heart (except anything Playstation), I think the Xbox 360's wireless controllers are the best. They're nice and weighty without being too much, fit perfectly in anyone's hands, and in general just work really really well. If only the D-pad were better...
I really like the Xbox360 wired controller. Seriously, what other controller can you mod to dispense hot pockets without serious structural remodeling. It's also very durable, mine has taken a lot of punishment and only required a little cleaning here and there to keep it in good shape.
Myles, I think you nailed it with the Gamecube controller. I love my Wavebird, and still use it when I occasionally play Zelda. The N64 was decent, but it just felt like it had superfluous grips on it. I'm not sure I recall any games I played on the N64 that I used the left grip with the D-pad. *deep in thought* But my favorite is the 360 controller. Sony controllers just felt like I was holding a 2x4 with buttons and stuff.
I really like the 360 controller. It seems the be the only kind of controller that fits everyones hands and it has a nice weight without being over the top. I know this wasn't part of the question, but I've just got to point it out, the PS controllers have got to be my most HATED controller of all time. It's like they challenged themselves to make the most uncomfortable controller physically possible.
I agree with LikesCrazy. The 360 controller has really good form factor and fits nice in the hands. Besides fixing the D-pad and making the buttons clicky like the DSi I don't think I would do much to change it.
