I'm not really sure. I like both. They can both have ups and downs tho.
I really hate those soft apples which are like.. floury in their consistence. But I don't want my apples too hard either.
Oranges can have their downsides too, for example when the.. I don't know what it's called.. Those little ''pods'' with the juice inside of them. Anyway, I hate when they are hard. I also don't like it when they are too sweet, nor too sour.
But I choose apples cause you can use them for cooking and dessert, they can also have more variety (from what I know).
