Another thing to keep in mind is that the Sonata is longer if you want to learn all of the movements (if that matters to you) and perhaps requires more stamina.
this is a rare instance where the Chopin work actually beats out Schumann in terms of requiring maturity in interpretation.
Where have you seen any SChumann haters here?
This is a weird take. Chopin in general tends to be very difficult to play really well as you need access to so much, psychologically, to fully capture the emotional content of his music.
Anything you choose would be orders of magnitude better than Bob Schumann
The only Schumann anyone should be playing is Clara Schumann, and that is still cutting it too close considering what she and her hubby did to ruin our poor boy Brahms.
