Which is better Motul Rbf or Castrol SRF?

I used to use Motul RBF because of it’s high dry temp boil point. The issue is the wet boiling temps. While you give up a little on the dry boiling point, Castrol SRF has a significantly higher wet boil point and will give all around better protection from brake failure. This is the best brake fluid, street or racing.
