Huge longevity and projection, like the black edp, I would just say less floral and more rum and pepper, especially in the opening it burns my throat.
After hours, it becomes almost the same as the edt.
In my opinion, this is more masculine, if I had to rank them, the Purple is the most floral with scents and easy to wear, the Black is complex with truffle, patchouli, and flowers, the Gold has almost no floral notes, intense patchouli, rum, and pepper.
They are all incredibly distinct fragrances, not for close encounters, not for closed spaces, and not in large quantities, you should try them before buying.
