CrazyA, oranges suck. They really do. When you go get a bag of oranges from the grocery store, the odds are that you got a crappy bag which isn't ripe and got painted orange. Sure, when you do FINALLY get that bag of awesome oranges, they're amazing, but let's face it: Oranges in general suck.
Apples, on the other hand, are like the Chuck Norris of fruit. Not only are they awesome, but you'd be hard pressed to pick up a bad bag of apples from the store. They just don't sell bad apples. Except, of course, the Red Delicious apples, which are spawn of the devil. Also, who peels apples?! All the flavor is in the peel! If you're making apple pie, then I can understand that, but no one who truly enjoys apples peels them. That's got to be some sort of sin.
The next thing to consider is that there are so many different types of apples. Sure there are tangerines, clementines, and other things like that, but those aren't actually oranges. There's only one type of orange, and it mostly sucks. However, apples come in different varieties to please the tastes of many people. Cortland apples, my personal favorite, are more tart and crisp, and go well with cheese, while Pink Lady apples are sweeter and more firm, and are delicious by themselves. There are Jonathan, Michigan and McIntosh apples, which are amazing baking apples. Golden Delicious, Granny Smith, Honnycrisp, Fuji, Gala, I could go on for hours. Each with its own unique flavor and texture.
There are also many, many different things that you can do with apples that you can't do with oranges. Apple crisp, pie, turnover, fries, fried apples, applesauce, etc. I mean, who ever heard of an orange pie? I'm sure someone has done it, but it comes nowhere close to apple pie.
There is just no comparison. Apples are clearly the superior fruit.
