These days I’m more fond of savoury when it comes to pie, so I’d say a good, fresh pork pie with the jelly only just set.
However my NSFW answer is

Savoury: chicken pie. Locally known as “empadão”:
Sweet: inverted apple pie aka tarte Tatin:
Blueberry, and it’s not even close
homemade. fruit. with a lattice top. anything else goes
i’m a big rhubarb fan, i do an excellent rhubarb and canned peach pie, i never measure it but a can of drained sliced peaches, cut each slice in half longitudinal, so they’re thinner, cut 2 stalks of rhubarb thin on a bit of a bias, sometimes i don’t use it all, toss with a couple tablespoons of flour, pinch of cinnamon for flair, and my secret is using brown sugar instead of white, just a couple tablespoons, bake until the crust is cooked and it’s fine with me if it’s pillsbury, you will have to cover the edges w foil before the end, cool for an hour minimum, serve al la mode
