OCC and OpenGL

Has anyone ever compared OCC with OpenGL?
can anyone share the information about what are their advantages and dis advantages? Thanks a lot

There is nothing to compare. OCC uses OpenGL as its graphics sub-system. If you are looking for a bare-bones graphics subsystem, use OpenGL. If you are looking for a solid modelling library, OCC is a reasonable choice at a reasonable price.
