I've listened - following George's list - to the late three sonatas interpreted by Schnabel, Gulda Serkin, Pollini, Kempff, Richter, Yudina and Brendel.
Neither of these sounded "wrong" or plain inferior to another one considering the pianist relationship with the music; but if I should rate them on my taste, I'd say that Richter is the only one who almost disappointed me - some passages are blury, he takes the Allegro Molto from Op. 110 with exhausting slowness. Schnabel is the more literally visionary interpreter, so maybe Schnabel's late 3 sonatas may be considered quite philological, considering the adherence to the original poetical issue.
