I think they both smell quite different actually!
Ambre Precieux is much sweeter with vanilla and a touch of powder, and very good longevity and sillage. When wearing it I feel like I'm radiating a bright golden glow!
Whereas, Ambre 114 is deeper, subtler and more resinous, with a hint of spices and rose (I think). When I'm wearing 114 I feel like I'm wearing a warm spiced cloak of scent. Complex, but closer to the skin.
For me... I find Ambre Precieux a bit too cloyingly sweet and feminine for me. Ambre 114 is currently my favourite amber, which fits perfectly in between Ambre Precieux and Ambre Sultan.
