Interesting, I expected everyone to really say GC controller. XD

I have to definitely try out the other methods.

I thought classic would be best because it would be similar to GC but wireless. Sadly, Nintendo fucked up and you cannot control movement with the d-pad so I consider it worthless.

I love the wiimote sideways because it is so easy to teach non-gamers and no work to setup.

The GC controls are either wired or require AAA batteries which I cannot recharge :(

Gamecube controller all the way for me.

 I really thought this as well.  I might have to go back and try the Wiimote and Nunchuck again.

Wiimote and Nunchuck once you get use to it its really good

It's hard for me to get used to the nunchucks but I'll eventually get used to it. The Wiimote alone is pretty good so far, I can beat up a LV3 CPU pretty easily, haven't tried further levels. I'm sure I can beat a LV5 CPU with that skill.

I'm currently trying the classic controller now. It's pretty good (Defeated a LV5 CPU) if you don't mind using the bottom left analog for the movement. Personally D-pad isn't a good idea for smash anyways IMO, but maybe that's just me.

I am starting to love the idea of using other controllers, it makes Brawl feel more different from Melee than it already is.

GC - i tried the other and I hated it

I've only tried the gamecube controller although I do plan on testing the wii-mote and buying a classic controller to test it out soon. The gc controller just feels soooo right after playing melee for so long. Smash really does worn down your controller :/

I prefer the Wiimote turned sideways also. I don't like using analog sticks for 2d games. I'm not sure why they didn't give the option to use the directional pad for movement on the GC or Classic controllers. I would love to use the Classic controller if that were made available. The directional pad on the Wiimote is tiny.

Wavebird for me, though I actually don't mind the Wii Remote only setup. The only one I haven't tried is the Classic Controller.
