Wickson crabs (
https://pomiferous.com/applebyname/wickson-crab-id-6690) are really delicious and grow vigorously, fwiw! That said (contrary to a commenter above), they are moderately susceptible to rust and some other diseases, so it's not a good choice for every area. Apparently amazing for cider, though. I didn't get more than a dozen fruit before I had to move from my last house, so I never had enough to try cider; I just ate them straight. I now plan to plant a Dolgo, a Chestnut, and a Trailman crab if I can find them all for my forest garden (all disease resistant in my area). All are supposed to be tasty crabs that also work well for jelly or cider.
Unlike many people, I do really love to eat intensely flavored, tiny apples straight from the tree, so I think I'm just a crabapple sort of person! I also just chop the sides off the core of an apple, which isn't much of a hassle. It's a little less perfect than a proper corer, but it's fast, and it works fine for small apples, too.
