I will compare Euphoria to Endless Euphoria, as they are quite different and each good in its own way.  Endless Euphoria, also by Calvin Klein, is a very pleasant floral fragrance, with a light set of overtones.  It compares well to Estee Lauder Pleasures.  And it lasts most of the day.  My wife prefers the Endless to the regular Euphoria because it is lighter and lasts longer.  However, Euphoria is one that I like more.  It is also floral, but it is bolder in its overtones.  My wife says it does not seem to last as long, but I wonder if that is because its intensity diminishes not the entire fragrance itself.  I think that the Euphoria perfume compares well to Beyond Paradise.  Both of these perfumes by Calvin Klein are very good, and I don't think you can go wrong by them.
