My experience is with original, older monos.
Recently snagged a mono first pressing of Mile Davis' "Round About Midnight" from 1955 and it absolutely wipes the floor with my other two stereo versions.
Another recent purchase was Barney Kessel, Ray Brown and Shelley Manne's "Poll Winners 3" from 1962?...one of the best sounding LPs I own.
I also recently rediscovered some original Mercury Living Presence monos and they are spectacular.
Again (and similar to current vinyl releases) pressing and recording quality will vary.
