I tested samples of H24 EdT, H24 EdP and H24 Herbes Vives on three consecutive warm days. The performance for all three is about average. For longevity, I got about 6 to 7 hours for the EdT and EdP while Herbes Vives was about 4 to 5 hours. Projection for all three was about arm's length for an hour or two. For me overall, the EdT performed best followed by the EdP (both were close) and lastly Herbes Vives.
H24 EdT is a really nice aromatic green fragrance. It's a pleasant, fresh green, not pungent. Some green fragrances are too much - smelling like your hands after pulling weeds from the garden. H24 is not like that, with the green accord being a smooth part of the overall scent.
H24 EdP struck me as more woody and less green with a more obvious touch of florals. The woody accord is also smoothed out here some, so it isn't sharp. H24 EdP also seemed a bit sweeter than the EdT.
H24 Herbes Vives ("live herbs") did not deliver a herbal experience for me. In the opening, I did not get much green or herbs but immediately the sweetness of the pear. (The EdT opens green while the EdP opens green/woody.) Over its life, it was also the sweetest of the three. Upon dry down, there was a more subtle green accord, but less than the other two. I did not get any pronounced cooling or refreshing aspect from the Physcool that I could tell.
All three H24's are sufficiently different that it wouldn't be redundant to own all three if you like them all. All three are masculine fragrances that would be pretty versatile. They are reserved enough for office use. The only restriction I'd say is they are really only useful on warmer to hot days or nights. I suspect on cold winter days, all three H24's would be lost and fade quickly away.
I preferred H24 EdT best and have added it to my shopping list.
