I have no idea, the easiest option would be to get to a starparty I guess and see some side by side for visual performance.
Hand figuiring is down to how good the person doing it is, I guess the only sure answer would to get an old and a new and get them tested.
I'm guessing the lack of response is because the people who have viewed the thread simply don't know, or just as likely, the question really can't be answered by anyone who doesn't have the particular mirrors to be compared.
An old hand-figured mirror could be a dud or an absolute corker, no way to know if one hasn't seen it.
