Using only traditional methods there are several "new" Swedish varieties, Aroma, Frida and Saga that are very nice - and especially Saga is absolutely fantastic - On par or better that international varieties Jazz, Pink Lady and Honeycrisp.
Some of the more traditional varieties are also sold more and for a longer period because of the improved storage, even though that I think they have a shorter storage window.
The real good ones, like Berlepsch, are hard to find here, though, unless you travel to a plantation.
Any other Apple variety just feels not nearly as juice and regularly too sweet for my taste - especially when you want to use them for baking.
Ambrosia apples appear to be a spontaneous cross of grandchildren of Golden and Red delicious apples.
