I have to disagree. The best apple pies use a range of apples. By adding different types of apples you add different texture and flavors to your pie. I will typically use 2-5 different types of apples and I bake apple pie all the time. I'm certainly no authority, just feedback I've gathered personally as the apple pie maker in the family.
The reality is most people can cut up apples and add sugar. The hardest part is the dough, the apples might not even matter, if the crust isn't good the entire pie fails.
