I think they are both extraordinary

but I feel that Gilels is solid and dependable, while Richter, despite certain eccentricities and strangeness in his playing, sends the listener (well me, anyway) on a journey to places never known or thought of before. He is in my top 5 favorite pianists list for sure, some of his interpretations are questionable but the good ones are simply beyond the capacity or ability of almost all other instrumentalists. And this makes up for the bad performances, and there are a few, Schubert's Sonata in a minor op.42 for instance; I don't get what he was after there....

It's very interesting to compare Gilels' and Richter's recordings of the Brahms 2nd Concerto, it shows both of them at their best, and illuminates the differences between them.....
