Its integral is simply the best. Make an experience: listen to the last three sonatas played by Schnabel and after Nat. No doubt: the clarity, accuracy and especially the beauty (the Andante of 30 !!), are on the side of the French. But there is a danger: if you listen to Beethoven by Nat, you'll struggle to hear other pianists in this directory (except Richter in the Adagio of the 29th, unsurpassable).
