For me,
1. Ashekenazy/Richter, both are extraordinary.
2. Horowitz
3. Roberto Szidon, a Brazilian pianist who recorded the complete sonatas in the 70's or 80's
I've never heard the Sofronitsky, but everything he does is brilliant, particularly Scriabin.
I've never heard Laredo's, but I do not care for her playing of anything, I can't imagine I would like it.
