The one big advantage to AFA is that 'it does what it says on the tin'. If you buy an AFA 80 you know what you are going to get (99 times out of a 100). If you buy a C8-9 MOC you run the risk of someone using a very generous interpretation of the C scale. We've all heard the horror stories.
Ok, AFA make mistakes, bubbles on graded MOC's can crack and are impossible to protect during shipping, if you get lots of pictures of an ungraded MOC before buying you should be ok, but the grade does provide a degree of certainty.
Whether it's worth the premium you pay is a matter of opinion.
