Early Stones. Because they recorded on Decca in the golden period.
Plus most later Stones is crap.
But OP appears to posit the original recordings. If you listen to LPs you have to look at MFSL (and some other reissues, very carefully chosen) for greatly improved SQ in many cases. I would cite for instance Beatles for Sale and Revolver as astonishing, and the original EMIs were good. Listen to I'm a Loser - Lennon is right there in front of you, his grainy voice perfectly reproduced.
