Who prefers the Quad 57s over the 63s?

It seems like most who have heard both, think the 63 is the more accurate, detailed, extended, and better imaging/staging speaker. However, there are some die hard 57 owners (including some high end recording industry professionals and reviewers), who believe it's the better speaker. They say the 57s are more transparent and has midrange no other speaker can quite match. And even go on to say it does better imaging/staging (may be they mean more natural) than the 63s. Any thoughts?
