I used to work at a grocery store, and actually don't feel the way OP does. Honeycrisp are fairly different, in my opinion. A fair bit tarter, and they have an almost fluffy light crisp texture. They even have a different cellular structure than your average apple, IIRC.

Though I agree that more apple varieties would be good, OP is underplaying the differences between the widely available apples. Growing conditions have a great effect in flavor and texture as well.
