Depends on your expectations, but not really. Freeze-drying is better than spray-drying, but not as good as concentrate, and none are worth the effort imho, mainly because of shelf life limitation. If I can't have espresso, Aeropress or pour-over from freshly ground beans, my expectations shift dramatically.
A months-old freeze-dried strawberry is edible, and better than many alternatives, but it can't really be compared to fresh fruit.
