It's really quite simple. An absolute perfect pair of fakies will never measure up to great set of naturals. There are some good fakies out there, but they don't compare, top to bottom, to naturals.
I don't know why people act like they can't see those big ass ugly scars underneath those misshapen titties. Oh, but I guess since they're big and fake, it makes up for all the rest of the issues, right?
