For a very sweet, store-able, late apple, GD is underrated because in the quest for strains that had no tendency to russet they destroyed its flavor. GD is extremely grower friendly and a very consistent cropper for a late. I prefer a more complicated apple but GD is a lot easier to grow than Mutsu, or Fuji, the most popular sugar apples around here. Older strains of GD are still very good multiple use apples for the home grower. Mutsu and Fuji will not give most home growers here an annual crop. They must be thinned hard and early to do so and are still going to give you light crops on alternate years- at least on the free-standing root stocks I’m familiar with.
