Kyle: Any polygonal representation of a sphere will be an approximation because polygons simply don't have spherical surfaces.
Catmull-Clark subdivision doesn't result in perfect spheres, but it is very easy to model with because there are no restrictions on the geometry. You can build any shape you want and smooth it with CC subdivision. You can add creases, softly rounded edges, etc.
Systems like NURBS can make perfect spheres but they can be extremely difficult to use due to the restriction that all faces must be quadrilaterals.
The Blender-style Quad sphere looks interesting. The plug-in doesn't seem to generate any texture coordinates though. I'm not quite sure how to handle the singularities at the poles. I'll take a closer look at it.
