I am wondering how you can compare the three in terms of quality (syntheticness), longevity and depth/character. Which fragrance offers the most in terms of making you feel good or confident?

Van Cleef & Arpels pour homme vs. Yves saint laurent pour homme vs. Mont Blanc Individuelle

It seems as though Van cleef & Aprels has been reformulated a couple of times, and is not as high quality as when it was first released. Does anyone know which years it was reformulated? Also has YSL ph been reformulated also? If so was it the concentrated version or the regular?
