The only relevant info for the lens quality may be in a form of MTF - and this is shown by manufacturers less often than snake's legs.
The Photozone reviewers are pretty matter of fact as far as I can ascertain. In a number of the reviews they'll often state the glaring flaws in often hyped models without poetic language (whatever that's supposed to mean).
Their own MTF and CA lab tests (I don't believe they're printed verbatim from the manufacturers) have been extremely helpful to me.

Hand's on would be very nice before making a commitment though.
