I'm probably going to use the classic because of more sensitive analog sticks, plenty of buttons, plus that d-pad you were talking about. With customizeable control schemes 3/4 controllers will be great. Wii-mote and Nunchuk are great too w/ shake Smash and rumble though.

Am I the only one who has all possible control schemes for friends coming over? I mean just for Brawl I've bought some controllers. I have 4 wii-remotes & nunchuks, 2 classic controllers, 4 gamecube controllers (w/ 3 extension cables so they reach the couch) so everyone can have their preferred control scheme. It's crazy how many ways there are to play.

Final Word: Wii-remote and Nunchuk or Classic Controller because they were made for the system.
