Honestly, for both the Opiums (men's and women's - the women's being newly reformulated for your info), the EDP's are superior scents to the EDTs...
Especially the men's: If you search on basenotes you'll find a couple of much contributed threads that say just that...
The men's EDP is strong, full of balsam's (Tolu and Peru), full of Cedar, Vanilla and Pepper (and I think some sort of blackberry!) and dark and heady... like a swirl of autumn leaves walking on the edges of Pere Lachaise cemetery on a cold winter's day as the sun starts its descent. It is a very atmostpheric scent and lasts in a sexy, smokey, temple or cathedral -ish way....
The women's is a bit too sweet and cloying for me to wear but I do love to get a whiff of it on a passing woman (or man)... it's very distinctive. Cinnabar (the colour, the substance) is exactly what i think of when I smell it... also orchids, frangipanis, gardenias, heavy resins, lace underwear... hehehe!
you gotta be some sort of queer as folk queen, heavily macho guy into being outright metrosexual, or just confidently experimental to try both these eaux des parfums!
but they are great

(in my opinion the revamping of the womens' Opium EDP is more acceptable than what they did to the glorious original Rive Gauche (shame, shame)... and the men's Opium EDP seems to have avoided that horrible fate as yet! It's still the same as when it was introduced)
