Some of the discussions that occur on this forum amaze me. As far as I know and have ever known there is no hard and fast criteria defining "best". I'm sure the determination of "best" varied from firm to firm and I expect that Purdey's concept of "best" was probably different than Greeners just as an example.
A long time ago some judge back when they usually had common sense stated. "I don't really think I can define pornography but I recognize it when I see it."
I'm fairly certain my own perception of "best" is in variance with others on this board but I certainly don't have any problem with it's use in describing the triplets that started this thread. They are outstanding in my book.
