I got my Wii U last october but I still haven't done the transfer. I'm aware that I can't use my gamecube controller with the Wii U, but are there any other cons beside this? Personally, I think it's much more convenient to switch between menus rather than between two systems, but I'm kinda scared that I'll miss the GC controller. Also, will Miis from my Wii end up in the wii menu or the Wii U mii maker?
