I don't know whether it is "the best" or anywhere near that mythical level, but the one I have is by the Choeurs et Orchestre de Paris under Daniel Barenboim, with Kathleen Battle, Ann Muray, David Rendall and Matti Salminen EMI CDC 7473422. It sounds good to me, but then what do I know, I have no other point of reference. Wonder what the previous posters think of this recording?
