I have a D'Arcy Spice apple tree that I got years ago from Deacons.
It was supposed to be trained as a fan shape, but I lost a few branches for various reasons and decided to retrain it as a half standard. It is now a very productive tree, but I have to be careful not to let it overbear on years where it is literally dripping with fruit, or else it is inclined to biannual bearing. This year is a heavy cropping year, so I have been thinning fruits like mad! Very tasty apples as well, one of my favourites.
Lord Lambourne is another super variety, so that would be my pick of the three, but I haven't grown the other two you are thinking of.
