Gamecube controllers are probably the best controllers for non-motion play, although I love the Playstation controllers too.
Motion play is up to debate, but so far it’s the Wiimote (since of course, no other motion controller besides the Power Glove has been out). Playstation Move lags a bit apparently, and if Project Natal does not live up to it’s seemingly magical trailer, you may say “Bon voyage” to that idea.
