Fairly self-explanatory...Ed
As for least satisfying, (please don't hurt me anyone for saying this, only my opinion! :-/), I would say some of Mozart's Sonatas. After sightreading one of the sonatas, one would get the impression, "Wow, I just wasted some time on that!"
Hey, if you miss a note in Chopin, I'll catch you...I find that playing Mozart's Sonata in A is very satisying to play out of compared with all my Chopin repertoire.
