I wish I could help, but can't. I own Omar Sharif Pour Homme, Omar Sharif Pour Femme, Ignis, Nubiade, and Conviction for Women, but have never gotten a bottle of Conviction for Men. I bought all mine locally here in Saudi Arabia but unfortunately have never seen the men's version of Conviction.
I will say that the others are all very good, especially the earlier ones. The women's Conviction is a nicely balanced mixed floral with a vanilla and wood base, attributed to Mark Buxton. I would expect Conviction for Men to be on the same level.
