A trio... of sorts

I thought I would share with you a recording of the third movement of Beethoven's Moonlight Sonata. Three video recordings have been spliced to create this: live recordings from Murray Perahia, Willhelm Kempff, and Daniel Barenboim. These three rank among my top ten or so for the interpretation of Beethoven Sonatas. But of course I prefer one over the other; I'll reserve judgement. To me, listening to this recording isn't effective as a whole because the style differences are so drastic. However, the differences in interpretation are more obvious when presented this way. What are some of the individual traits you notice in each performer and which do you prefer?
