chanel would be categorically my 1st choice (sycomore, cuir de russie, eau de cologne, coromandel, antaeus, etc, etc)
followed closely by cdg (too numerous to mention, they would be the only ones that i'd be tempted to swap places with chanel, completely concur with alfarom, their perfumes are considered niche but the house is designer)
then dior (eau sauvage, the entire la collection privee line, homme, fahrenheit, jules, dune, etc)
and hermes (bel ami, equipage, almost the entire hermessence line, terre d'hermes, rocabar, eau d'orange verte, voyage, etc).
