The procrustean way is subjective, words as good, derisible, better and superior are relative to the eye of the beholder as well.
Nevertheless, the fact remains that all proof coins were struck at the USA MINT and struck at different stages. Using worn dies actually accentuated proof coins. In fact, worn dies did not distract or create inferior coins it produced brilliantly mirrored finished coins!
