IMO Cappooch is a heavier scent than the classy Eau Sauvage.
Cappo is leathery, spicy, a real 80's warhorse.
Eau Sauvage is nimble, elegant, more lemony. It is in the classic Eau de Cologne style, but with more than usual depth.
I don't care for Cappo but you may like it -- but it is no sense similar to Dior's ES.
