The tag on my Lattarulla (Italian Honey) tree from Edible Landscaping also lists Danny's Delight as an alternative name. On their website, under Lattarulla, they say:
"King fig seems to be the same as Lattarulla. Also called Danny's Delight, this fig has ripened its fruit near Lake Michigan outside. Figs are large, pale green to yellow, sweet and delicious."
They sent a fairly large tree with a number of ripening figs on it. The first was ripe on July 16, was pale green with a pink center and tasted mildly sweet with a slight hint of berries.
My Desert King tree (Dave Wilson Nursery origin) seems completely dead now, so I can't really compare. It couldn't take the heat here, must be a cold climate fig in spite of its name.
