If you get a chance, try WineCrisp. Loads of flavor and stubbornly crisp. The things keep for months, even in less than ideal storage (such as a fridge), and even after losing a great deal of moisture retain a snappy bite.
Only real downside is that the appearance isn't very flashy; they're the russet potato of modern apples.
I used to always get Pink Lady, but in the past couple of years I've found Kanzi to be better. And somehow my partner gets less allergic from Kanzi as well.
Their green skin can help with inflammation as it contains enzymes that protect T-cells. They're helpful to prevent diabetes and are recommended for diabetics to eat. They're high in phytonutrients and are apparently have the best antimutagenic potential of apple breeds. I think most of their benefits are shared with other green apples.
They've got high fibre content whilst being lower in sugar than other varieties and are good for gut bacteria.
However, the best apple to eat is one that you like as it's better to eat any type of apple than none.
I find that at my local grocery store in NJ, Cosmic Crisps to be more consistently good than Honeycrisps, despite being less crispy. But the best Honeycrisps are better.
Sweetango is also consistently flavorful and crispy and normally better than Cosmic, but the availability is what's inconsistent.
(And a Fuji apple I had in Japan was as good as the best Honeycrisps)
Cosmic crisp is amazing. I also like a good Fuji, though they're not as consistently good. Jazz and Ambrosia can be good as well. It's nice that we have so many varieties to choose from now. When I was a kid it was either Red|Golden "Delicious" or Granny Smith.
This is the way... there's research already at WSU for when the Cosmic Crip runs its course and the world is ready for the next apple with the same basic characteristics.
Don't wait too long though! Because then they get a soft jammy texture that some people absolutely hate. Transitioning into full goo eventually. (Yes that's the case for fuyu too, not just hachiya).
Also some fuyu can still be astringent when very firm / underripe.
Put it in a blender. Lemon juice optional. This will destroy the slimy texture. Fill a glass with the mix and then add cream on the top and you will have a spectacular dessert.
Persimmons are three (four?) totally different fruits in one.
I’m fully aligned I eat apples for the texture above all else, with flavor being important but nothing close to how much crunch eat bite has.
