Why is Cheez-It so good?

I'm curious, what is it about Cheez-It that makes it so irresistible? Is it the perfect balance of cheesy flavor and crispy texture? Or is it the convenience of having a snack that's ready to go straight out of the box? And why do so many people seem to have a strong preference for Cheez-It over other similar snacks? Can you explain the science behind why Cheez-It is just so darn good?
