Best Scent: Chanel Blue/YSL L'homme toss up....I enjoy them both
Crowd Pleasing: Chanel Bleu
Versatile: YSL L'homme
Flip a coin on this one...I think they're both great fragrances. I'd give the edge to L'homme on versatility alone and the fact it's not nearly as popular as L'homme. Either will suit you quite well.
