Yes 10 times over. Unless you were into waggle, then I don't know how the hell you could disagree. The Gamecube was a CORE SYSTEM. What do I mean by this? Take a look at TP. Gamecube version uses a real controller and works where as the Wii version, you're waggling... yes... waggling to swing a freakin' sword lol.
I'll take Gamecube any day. If you could translate all of their biggest games on Wii to use Gamecubes controller though, then it gets harder to pick.
