Both

Personally I prefer the Wii with its extensive library of both Wii and GC, and how easy it is to mod, but so far I'm having a great time with the Wii U. It may be a commercial failure but it's still got tons of great games and a fun gimmick

this is lowkey like saying "hamburger patty vs hamburger" bc the WiiU can do everything the Wii can (with some homebrew helping hands at least) that being said, WiiU (^o^)
