BdP is amazing. Others can tell you in more detail, but it is classy, elegant, and the longevity is very good. I just bought a bottle myself. Smokey at first; vetiver, lavender, spice, sandalwood. A bit of sweetness creeps in on the drydown, but it is always held in check. Just Right IMO.
Heritage and PdN - New York are sometimes compared to BdP. PdN is slightly less masculine than BdP.
Heritage and BdP will be staples not only in my fall/winter drobe, but I wear them whenever I want really (summer requires lighter application).
Hope this helps. the_good_life speaks highly of BdP, and many others also. Chime in guys and gals and help this man out in more detail. Good Luck with your decision.
