Teardrop, of those on your list I'm familiar only with Ambre Sultan, Ambre Precieux, and Anne Pliska.
Ambre Sultan is an atypical amber in that it hasn't the sweetness of most ambers but is dark, smoky and incense-laden;
Ambre Precieux is a brllliantly well-balanced amber, not too sweet, not too dry, with aromatics in the top that add a welcome airiness and "spikiness" to the composition;
Anne Pliska is a cuddly sweet amber with a beautiful bright bergamot note up top. I don't often get compliments on my frags other than from my husband but I never fail to get complimented on this one. Others can smell it on me and comment favorably long after I think it's faded and gone.
I would be remiss not to mention two other fabulous ambers: Etro Ambra (golden-sweet, resinous/incensey) and i Profumi di Firenze Ambra del Nepal (rich, sweet amber with vanilla and a nice hit of dry cardamom).
Enjoy your samples!
