You're absolutely right to connect Euphoria with Angel -- it's one of the leagues of Angel imitators (and I like Euphoria; it started my fragrance journey a few years ago).
But there are lots of women who simply don't care for the heavy combination of fruit and patchouli. Some women prefer delicate florals. Or classic chypres. Or clean musks. Or citrus. Some women just really hate patchouli.
And then there are others who may not like it in part *because* it seeks to imitate Angel, because it's merely derivative instead of being original. I get that point of view, but, for me, I like what I like regardless of whether it's a "reference" fragrance or whether it was influenced by something else. I personally prefer Euphoria to Angel because I don't care at all for the chocolate note in Angel. But I vastly prefer Robert Piguet Visa and HdP 1804 (George Sand) (two other Angel imitators) to both Angel and Euphoria because Visa and 1804 don't smell (to me) nearly as synthetic as the other two.
At the end of the day, one's reaction to fragrance is very personal and very subjective. You may not ever know why any given person doesn't like a fragrance unless she tries to explain it.
Something else I've noticed is that a number of the men who post in the Basenotes Men's Forum seem to be much more preoccupied with the question of whether *other* people like a particular fragrance or whether they've received compliments for a particular fragrance (witness the 87-page sticky thread in the Men's Forum about which fragrances are "female" compliment-getters AND the 11-page sticky thread in the Women's Forum about which fragrances "chicks dig" on men). There is NO corresponding sticky thread in either forum in which women are asking which fragrances men like to smell on women. There may be an individual thread on this topic every now and then, but they tend to die a mercifully quick death. This is admittedly a generalization but, among the women who post on Basenotes, there seems to be much less of a concern with what other people think (or find sexy); we generally are more interested in whether *we* like a fragrance for ourselves. Of course, if a significant other really *dislikes* something, many of us will wait until he/she isn't around to wear the offending fragrance. I'm still trying to figure out if this phenomenon is age-influenced, gender-influenced, or both.
