I have not heard either. I only buy SACD’s if low price, perhaps find used.
I have 2 lps of FNSF, in terrific shape and CD version, I convince myself I prefer the vinyl.
My perception of the advantage of SACD is reduced noise floor, nearly black noise you could say, which I expect the 3 guitarists would benefit from.
Rumours, the material, words, the music, I’m not so sure it would be as big of an advantage
