Schubert 90 no.3 or Chopin 27 no.2

[wzm]

Between these two, which should I learn first?  I want to expand my rep.  By now I've learned too many easily recognizable pieces and want to learn something different.  Although these pieces are well known among pianists, I like the fact that they're obscure enough that the general population hasn't heard them, or if they had, wouldn't make the connection with my playing.  I've sort of been going that direction lately.  Recently I've completed Bach's b flat minor prelude,  Chopin op.28 no.3, and you know I had to learn that Gluck/Sgambatti.

So which way? Chopin or Schubert?
