Acqua Classica Borsari is sort of an EDT version of the classic citrus cologne like Acqua di Parma, which is quite high-end in the cologne field. ACB can't compete for beauty or refinement, but it is not really the same kind of fragrance even though they are both citruses. ACB doesn't have the clarity or definition of AdP and its herbals - thyme and sage - are warmer and less distinct than the rosemary of AdP. ACB goes through a rather typical evolution of pyramid steps including a drydown of leather, vetiver and moss that lasts a few hours while AdP concentrates on the purity of a short lasting clean citrus / rosemary accord extended into the purity of a rose note and a light, comparatively shorter lasting white musk drydown.
Acqua Classica Borsai is competent, pleasant, and longer lasting. Acqua di Parma is beautifully clear, wonderfully refined and shorter lasting.
Oh, and Acqua di Parma is a heck of a lot more expensive than Acqua Classica Borsari.
