Michel Beroff, specifically his Denon recordings, though his EMI recordings are excellent as well. There is a new-ish, third release of the Preludes on Lyrinx from 2015, but I've not heard that yet.
Other notables are Michelangeli (DG or any of the multitude of live recordings), Jacques Rouvier, Jean-Rodolphe Kars, Walter Gieseking (his 1930s recordings, in particular), Ivan Moravec, and Daniel Ericourt (albeit in poor sound).
Among young pianists, Francesco Piemontesi's recent release of the Preludes is superb, and though she has not recorded any Debussy yet, I heard Lise de la Salle play six of the Preludes last fall, and she was up there with any name you care to mention.
