Nobody including JS Bach, Mozart, or Beethoven, would have achieved as much as Schubert had they died before 32. So Schubert is the GOAT. Agree or disagree and why?

Edit: Schubert is not my favorite composer, in fact he never was, although I admire his works. Also for past decade I've become much more enamored with 20th century classical music, which is what I mainly listen to these days. But whenever I think of Schubert I think he's just too amazing for an almost 32 year old.
