I just came back from the mall today and I tested both 1872 and X.
1872 - Basic citrus. Nothing special to me. In fact, it reminded me of Armani Pour Homme combined with Annick Goutal's Eau de Hadrien. When I got home I tried smelling my wrist to further analyze it, but I was disappointed that the smell already faded. That was less than 4 hours!
X - This one is good but not worth the price tag IMO. It's spicy and sweet. I detect nutmeg and clove in the drydown among other spices. Maybe it's just me but I also smell a slight hint of tea.
I haven't tried #1 because there's never a tester on display. But all in all, I think you could find better scents out there for a fraction of the price.
