i didn't directly compare the two formats but on basic listening i was pretty sure they had the same mastering and (unfortunately) the same MCh mix, which to my mind is really not good and doesn't do the material justice, surprisingly so for Don Murray since he previously did great Quad mixes (O'Jays "Ship Ahoy", Johnny Mathis "I'm Coming Home", Spinners "New & Improved" and "Pick Of The Litter") and subsequently did great 5.1 mixes (George Benson "Songs & Stories", Lee Ritenour "Six String Theory").. ah well, can't win 'em all i guess
