Quad sphere vs UV sphere, which should you use?
Well, for subdivision surface modelling, a quad sphere is the ideal solution since it subdivides nicely. A UV sphere on the other hand has nasty pinching artifacts at the top and bottoms caps due to the triangular poles.
Fortunately, creating a quad sphere is as simple as subdividing a cube, and running a to sphere operation with alt+shift+s, creating a quad based sphere that will subdivide perfectly. 😁
