I remapped the UV coords based on the spherical projection of the mesh after subdividing, so there should be minimal distortion, especially compared the UV sphere. There is a slightly higher density of vertices where the edges of the cube used to be, but it's small compared to the UV sphere's extreme convergence at the poles.

In planetary rendering circles, the cubified sphere is a great method and I'm glad he went over that here.
I should say you do get distortion where the cube faces meet at the edges. May or may not be a problem depending on how your texturing.
