I happen to like Red Delicious since they produce a satisfying crunch without being tart (like green apples) or mushy (like gala). I'm surprised this article is using a personal preference to criticize an entire variety and industry.
I liked Red Delicious back in the early 80s, but I noticed by the late 80s that they were becoming less flavorful, and tougher skinned. Now, the crunch and the visual is about all the red delicious has going for it.
I haven't seen Jonagold mentioned, but it's another one I like (though it doesn't store particularly well).
