Is it underrated? A lot of folks here and elsewhere like it, and I am certainly one. No, I do not think it rises to the level of Terre d'Hermès or Sycomore, but those are lofty standards to hold RMW to. Not being as well-regarded as those two masterpieces does not make a scent underrated to my way of thinking. As for Grey Vetiver, I would take RMW over it any day of the week.
