Mark Birley vs M7

Mark Birley is remembered fondly by the r/fragrance community as a sophisticated oakmoss-centered woody chypre that has proven its staying power by remaining a favorite among serious collectors for decades. The fragrance's discontinuation is widely considered a tragedy, with community members actively searching for remaining bottles and cherishing empty vials as memories of this exceptional scent. Its rarity and the death of its founder make it a highly sought-after collector's item that few can still obtain.

M7 appears in notable fragrance critic rankings and is appreciated by experienced collectors, though it remains a niche choice rather than a mainstream favorite. The fragrance seems to appeal to those with refined tastes who seek distinctive options, though limited availability of the original formulation is a noted concern.
