Here's a nice write up about it by esha: http://esha.at/Knowhow/Knowhow_E/Material_E/material_e.html

The only real difference I'm seeing is that .pz2s can't be used on props unless there's a figure in the scene, which is a downside. But as far as the material settings and such being different, I'm not convinced that .mc6s are better. Also, that page says .mc6s can't be used in DAZ. I appreciate the information, but I still don't understand why .mc6s are better.
