Unlike baking apples, we don't need to be as concerned about whether or not they hold up to the heat. We are cooking them down in the pan so they caramelize in the sugar, but no matter which you use, it's more about taste than it is texture. Granny Smith apples are nice and tart which is a great balance to the sweetness. Gala and Honeycrisp are a little sweeter, and you can't go wrong with Braeburn or Golden Delicious.
