To add to other answers there is one badass of a thing that you can do on Gamecube version and not on Wii version :
Load your spin attack while on Epona's back. Wich makes Link raise it's arm and sword in a very nice stylish effect, with some sparkle going along the sword. When charging toward enemies with the B button pushed it gave some LOTR felling that i regret they removed from Wii version
