Easily Wii simply because it has more notable games. The Wii has games I can still enjoy playing now, I don't feel that way about many N64 games.
N64's significance is mostly nostalgic. That was a time when major innovation was happening in 3D gaming, but innovation and great games aren't the always the same thing. Not much of the N64 era aged well.
I look at the 7th gen as period where developers really learned from past generations and started creating much more refined and balanced games. The Wii is part of that generation. Notable Wii games have and will continue to age better.
Honestly, I'd take Wii U over N64 as well for the same reasons. More notable and refined content. But neither Wii or Wii U or were around while developers were creating innovative content on N64.
