Planning for Apples - Lord Lambourne or Liberty?

It's been awhile since I've posted, but I've moved into a house(!) and am starting thinking about landscaping. It's (unfortunately) in an HOA, so I can't go hogwild, but I want at least to plant a couple of apple trees, some blueberries, and maybe a serviceberry. I've been investigating apples because I eat an apple a day and I'm very particular. I like extremely crisp apples that tend towards very tart (my big four are: Honeycrisp, Pink Lady, Lucy Glo, Lucy Rose). I could try to go for those, but I'm also interested in unusual varieties. I've read that Lord Lambourne and Liberty are two that would be good, and Liberty particularly as a homegrown apple. However, the apples that I can legit buy and taste are few and not varied at all, even at the farmers market. Can anyone here who has tasted Lord Lambourne or Liberty please let me know how they compare to the big four, particularly the crispness in texture (I despise mealiness)? I appreciate the help!

Neither of those leans particularly tart honestly. Lord Lambourne is quite sweet and aromatic, good apple but probably not what you're after if you like Pink Lady or Honeycrisp. Liberty is decent for disease resistance but fairly mild in flavour. If you want that crisp-tart thing in a manageable tree, Braeburn might be worth looking at. Closer to what you're after and reasonably disease-resistant compared to Cox.
