Acqua di Gio PROFONDO is probably my most favorite of all. Acqua di Gio PROFUMO is very similar to Profondo, both having the same blue acqua di gio DNA, Profumo is more casual and daily office or outdoor scent. The same can be said for Profondo, with the exception that to me profondo is a more sexy scent when comparing the two! they both lasted on me 4-6 hours, which is fine with me. Profondo has that sexy edge I really enjoy and would choose PROFONDO over PROFUMO.
