Simcha's got that "ch" loch sound -
Aliza's alot more user-friendly and has a pleasant meaning. I think it works fine with
Paolina (a lovely name) despite the mix of ethnic origins.
Yasmina seems a bit too much of a good thing to me, and unlike
Yasmin I feel it almost inevitably runs the risk of being shortened to Yas.
Hilda strikes me as hard and unattractive, and fully deserving of its present retired status!
