I'm curious which of the 4 play styles will be the most comfortable. The gamecube controller I'm sure will operate pretty much the same way it did with melee, and the retro controller attachment won't be too much different than that (although the left analog stick might get annoying)....

however I can almost see the remote + nunchuk combo being really easy to work with.
On the plus side, you can probably control the special and standard attacks with seperate fingers (thumb for A, trigger for B), but you lose the quick-grab that your index finger would otherwise control with, say, melee.
