I have tried two brands: American Almond Company (of Bklyn, NY) and Odense (Danish).
I wanted to like the former brand (I live in Bklyn!), but it seems to me that it has too strong of an artificial "bitter almond" flavor.
Odense tastes purer, and is more expensive. Their web site also features such excellent dessert ideas as the "Witch Fingers - Scary Fun For Grownups" (!) pictured below.
Any other brands you've tried?
