Why Super Mario 3D World is much, much, much better than Super Mario Galaxy

[iLikeEggs]

I think Galaxy 1/2 and 3D World are the pinnacle of 3d Mario and are much, much better than 64 and Sunshine. Still, I could see someone preferring Galaxy over 3D World and vice versa, but I cannot understand how either 64 or Sunshine are better than them (and I still own my original launch day copy of SM64, but that game has aged so so poorly).
