None, since I think Chopin, as great a composer as he is, is very over discussed at PW. I get the impression that some posters are ignoring much of the other great music from the piano literature.
He's sort of our immortal god as pianists. His body of consistently great
music is why he so talked about. No other piano writer managed to do that.
I dunno - from where I sit, Bach, Beethoven, Brahms, Schubert and Schumann are very much in the same league as Chopin when it comes to solo piano works, and Mozart too when factoring in piano concertos.
Also to be brutally honest, as a "complete composer," Chopin is overrated. He couldn't orchestrate worth beans. If Beethoven or Brahms spent all of their energies exclusively on solo piano, they would have been greater than Chopin ........
Well, we don't really know that.....and actually all three of these gents were geniuses. Beethoven and Brahms clearly were more "complete" composers in that they consistently created masterpieces in symphonic, choral, chamber music, and solo piano/concerto literature. But that doesn't make Chopin "overrated" or any less "great" just because he focused primarily on the piano.
