Golden Delicious can also get mealy, but quality varies a lot. As a kid, they were my favourite apple, but as I got older, they got softer and more mealy. Or maybe they were always mealy I only started noticing it then.

I don't buy them anymore. When I buy apples (which is rarely), I usually get either Jonagold (cheap and good enough), or Gala or Braeburn when I want something better.
