I double-dipped, and I love the portability, the 3D, etc. But one thing puts it heads and shoulders over the original: BUTTONS.
Eh, I'm no waggle lobbyist, but I never once died because of waggle problems in the Wii version. And the roll only activating on certain frames feels way more clumsy on a button than it did with waggle, but I can't fault that on the port since that's how the original worked
I do love the portability though, and the 3D is pretty nice
