I've had some spectacular Golden Delicious apples. I hypothesize that these otherwise mealy apples in the right condition have a soft pearish texture rather than a crisp cucumber-like one, but it is a fragile structure that degrades more rapidly.
Down here in the Netherlands most Golden Delicious are green, only seldom are they yellow. Mealy is when they are not saved well, more often they have a bit of bite. And juicy they are. It might differ per region.
