I tried (on my arm): CK One, CK All, CK Be, CK Everyone, CK Man (I still need to try CK Shock, which should be the best one)
All the Fragrances above are more versatile and can be used for every weather/occasion but have very poor performance besides CK Man, which performs good/very good but more of a night fragrance for me.
CK One: citrusy/versatile
CL All: it starts citrusy, becomes sweet
CK Be: Also versatile, but it smells more soapy.
CK Everyone: citrusy/versatile
CK Man: Starts dark, becomes fruity-sweet, ends with sweet/woody. The only Fragrance that I could still smell strong on my arm after 3 hours (and still going strong). For me it's more of a night/autumn fragrance than a day/summer one. I'm very picky about fragrances, still love this one.
disclaimer: fragrance noob here, so I might not get all the smells correct.
