Which vinyl to get?

[StevenSurprenant]

Moody Blues - Days of Future Passed

PINK FLOYD - DARK SIDE OF THE MOON

There are different pressings, but is one better than another. Which ones?

Thanks

Moody Blues original pressing, common and cheap. Pink Floyd a zillion different issues. Maybe Michael Fremer of" Analog Planet "could say. He knows so much it is disgusting.
