I don't have many OCs, but I like this Mays. To me, the value of the qualifier is that you know this is essentially how the card came out of the pack - according to the eagle eyes of PSA at least. With a 7 (or whatever it would be without a qualifier) you have less information about the overall condition. Of course I would know the centering contributed to the grade, but I wouldn't know it's the only real flaw PSA found.
