I lost my taste for sweet about the time I turned 18, and I’ve never been big on fruit. I still do appreciate the Granny Smith - tart, crisp, sour, delicious.
I have hated the Red “Delicious” since I was a little kid. These foul things always come out tasting mealy and feeling mushy. Seems like we always got slices of these in school lunches, but Lord, what a miserable apple.
Mutsu for me as well. I have a hard time finding them these days, but I used to be able to get huge ones at a farmstand where I grew up. Impressively tasty apples. While honeycrisps are quite nice, and Granny Smiths are reliably tart and crisp, none wow me the way those mutsus did.
We live near a family run apple orchard. Variety is what I like. Gala, Fuji, Cameo; hell, even an apple off the tree in our yard (unknown old variety) is good.
I just now voted for 'em.
They’re wonderful (despite the stupid name) and taste like a cross between what pink ladies used to taste like* and honeycrisps.
*Last few years, pink lady apples have seemed bland and kinda…mushier.
Aha! There was a poll coming. Now I understand! 
Still Honeycrisp if I had to live with only one. Which I couldn’t.
Red Delicious, because I really don’t care much for apples and they are the most bland of them all. I also don’t like the texture of an apple, and Red Delicious apples have the most un-apple-like texture of them all.
Even before I read your quote, I had voted for Jazz, so my vote isn’t just for spite. I think they’re similar to Honeycrisp but sometimes HC gets mealy and soft.
Another choice not on the list is the University of Minnesota’s successor to its Honeycrisp breed, SweeTango (their spelling, not mine). Again I think they get soft too quickly after picking.
Honeycrisp. Accept no substitute.
When I had friends over for dinner, I had a blind apple tasting for dessert. I bought several apples, cut them in quarters and presented them on little plates with a number. Everyone had to pick their favourite, and then I revealed the names.
Pink Lady was a winner in that contest. But it depends on the season, of course.
That’s my experience with Honeycrisps, too – if you have the words “honey” and “crisp” in the name, I would expect an apple that’s particularly sweet and particularly crisp!
Winesap, by God! None of this mealy “Red Delicious” twaddle!
Tasty enough, but getting a giant ant to share its apples is a real pain.
I’m joining in with the other Macouns. But now I have to go try a Northern Spy.
Granny Smith, Honeycrisp (but only in season!), and one I for some reason I hadn’t tried until now, the Fuji. Last time I was at the store this display of Fuji apples was calling to me, so I had to buy a few. Fantastic.
Honeycrisp. Definitely Honeycrisp.
Then Fuji, when Honeycrisp is out of season.
Pink Lady is real good, too, if I’m in the mood for a little tartness. I like that they are usually crisp.
Braeburn isn’t the greatest flavor, but also usually crisp.
If a Macintosh is crisp then it is awesome.
Red Delicious is usually not good, but the 1% of the time it’s good, it’s damn good.
Empire is not on the list, but that’s another one I’ll find myself eating.
I like Spartan, which is a lot like Fuji or Gala. I keep hearing good things about Honeycrisp, but I don’t know if I’ve had them. The picture on the Wikipedia entry for them certainly looks like it’s a good variety. If you slice them, do they have really white flesh that often picks up pigment from the peel?
Mutsu, Cox’s Orange Pippin, Gravenstein, on the west coast. But real east coast apples are better. Northern Spy for one. It’s been a long time since I was able to graze in a New England orchard.
Grocery store apples are between boring and unacceptable, normally. All of them.
Honeycrisps closely followed by Pink ladies. If your Honeycrisps are dull and mealy, you should probably find a new grocer.
Gravenstein is my favorite, but I’d guess that most people have never seen one. My favorite from the list is Pink Lady.
