I'm partial to Pierre Hantaï's second recording (on Mirare), though his first record seems to be better-liked among some reviewers. If you can track down Scott Ross' recording on Erato (or Virgin Veritas), then that is a fine choice, too. If you can get Rousset's version on Decca, then you'd be pretty happy, too. Really, for my money: Hantaï, Ross, or Rousset - take your pick.
