Some things I would also mention in https://lean-lang.org/doc/reference/latest/The-Simplifier/Simplification-vs-Rewriting/#simp-vs-rw:

  • simp never creates side goals, and can only apply conditional rewrite rules if the discharger can prove the hypotheses
  • rw cannot rewrite with local variables (in binders)
