In no particular order:
Ungaro II - one of the best citrus-civet.
Bvlgari Pour Homme - my favorite designer stealth/discreet scent.
Hermes Hiris - one of the few designer iris soliflores that I really enjoy.
Capucci Punjab - favorite "powerhouse".
Yohji Yamamoto Yohji Homme - my favorite coffee-rum scent.
Honorable mention: Bvlgari Aqva - though aquatics are not a favorite genre now, this (and Erolfa) is one of the best, IMO.
