From my limited testing of the current Havana, I would say it has better sillage and longevity than the current Tuscany per Uomo. You want to know which has better masculinity ? I can't say one is better than the other, because they are both distinctly masculine in character ( but a woman could pull off either).
I still say that Tuscany per Uomo is the better fragrance. It just smells better to me. I like that it resembles a lot of the aromatic fougeres like Azzaro ph, Calvin edt/cologne and to an extent stuff like Rive Gauche pour Homme, Trumpers Wild Fern and Penh. English Fern.However, that does not mean it is dated, as it is a timeless classic to me. It has a nice dose of patchouli in the dry down accord as well. I just like it better and it really works well for all ages.
Havana just never worked for me no matter how many samplings I gave it. I still have a bit left in a vial and will keep trying it out here and there. Maybe I will pull it out once a year and see. I like the idea of the scent, but it just didn't jive with my nose. It really reminds me of Montana Parfum d'Homme and that is one that never sat well with me. Kind of a dry and spicy green tobacco leaf accord. I am not the best with notes, but that is about what I was getting.
