Schubert is kinda overrated
Schubert is underrated in my opinion, no matter how popular he already is. He's my 2nd favorite composer. Maybe it's just cause my teacher says she doesn't like Schubert. Just my opinion.
All piano stuff:
You can't say his music is overrated without hearing this, of course. I don't know anyone who has.
Classic Schubert. What a beautiful, mature piece.
Melancholy and has quite a finale feel, appropriate for Schubert's upcoming death.
Another popular sonata. Barren and dry at places but always somehow both emotional flowery in these locations
I've been really hung up on this one as of late.
If you're wondering, I really admire Uchida as a pianist. And yes, I do hold the unpopular preference of major over minor.

If you've listened to all those pieces then I can't really say anything else.
