I am probably the only one here who loves Original Santal. I also have a decant of Joop! homme, and the two are definitely not similar. I cant stand Joop homme! while Original Santal has fast become one of my favorite Creeds.
On me, Original Santal shows two faces.
In summer, the coriander and orange blossom are more prominent, and the sandalwood is clouded out by these two notes.
In winter though, the sandalwood is more prominent, and is evident from the beginning. I like sandalwood, so its been great wearing original santal this winter. I get a prominent sandalwood note with hints of coriander and orange blossom resulting in a great sandalwood scent.
I would recommend this scent, but definitely try before you buy.
