Best mono LP issues of Beatles records?

Not wanting to spend my entire life savings, I decided quite a while back to
opt for the early 1980's mono re-issues of all the Beatles' Parlophone LP's,
rather than trying to hunt down all the original issues.  Most of these I
either bought brand new when they were first released, or acquired very
clean copies on Ebay.

I have since bought a few original Parlophone 60's-era mono issues on Ebay
(albeit not first-pressings, as indicated by the matrices in the run-out
grooves), and tried a few back-to-back listening comparison tests with my
1980's re-issues.  Allowing for a bit of surface noise from wear in the
original issues, I still found that I preferred the 1980's re-issues, which
simply sounded a little cleaner and more open.  Maybe it would have been
different if I had access to first pressings, but I wonder.  Anyone else had
a similar experience?  (Please don't respond with any opinions on the
relative merits of mono versus stereo - I'm not interested!)
