Based on other artists during that period I have in my collection, the mono always seems to have a more organic, convincing sound than stereo presses.
Purely subjective otherwise, unless it's that awful hard left/right "stereo" I always go for the mono copy of any LP, especially late 50's-60's artists.
The tough part is finding a copy unmolested, for a price you want to pay.
