Apologies. The above long answer about pianists should have been to you. When I have extra time on my hands, I try to compare pianists playing the same piece. Listening to Schubert's Impromptus, especially D899, is when I realized I like Mitsuko Uchida so much. I have listened to that Impromptu by Alfred Brendel, Andras Schiff, Vladmir Horowitz, Artur Schnabel and others, and her fingers seem to possess so much more subtlety on that piece.
I do not, however, think that she is best on all pieces. She specializes in Mozart and I have heard pianists I like better than her on certain piano concertos. I think I would recommend Geza Anda as my overall favorite on Mozart's piano concertos. I think that was because he was conducting the orchestra as well as playing piano. I have a recording of Mitsuko Uchida also conducting the orchestra while she plays two Mosart piano cincertos and I liked thos a lot better than when Jeffery Tate conducts while she plays.
