I own the EDP & have tested the EDT! I much prefer the EDP! & here is why. The EDT is a nice offering from Guerlain which opens with a nice citrus burst, a tad of cocoa & woods. In the EDT version the citrus is the more dominant player. While it is nice, it does not last very long for me to get a full bottle! 4-5 hours max is what I get out of the EDT.
Now for the EDP! The first initial blast of this concentration is a heavy, yet sharp dry, bitter cocoa accord with a hint of citrus & woods. This concentration the dry, cocoa is the main player. It last @ least 10 hours on me & is indeed lovely! It leaves a nice lingering aroma for people to follow & its just awesome! Pure class here! For fans looking for a sweet cocoa note, THIS IS NOT YOUR FRAGRANCE! The only sweetness I may get from this is when the citrus & cocoa note collide.
I Would not really call the EDP a straight gourmand, because clearly it is not, but its more so a mixture between a gourmand/oriental if that makes any sense. Not for the faint of heart, or who is looking for something sicking sweet! The EDP is more mature than the EDT & for the $$$ its a better option to go with including the fact that the EDT has longevity issues compared to this! Kudos to Guerlain for this masterpiece!
