Is that so?

It fits with my understanding as well, but comes from investment grade bond ratings where AAA usually signifies the highest quality (i.e. the best chance of getting paid back). A AA bond is still a good bond, but it has a higher risk of default.

But in practice, I just see AAA as a “high budget production,” both in development costs and marketing. It doesn’t mean it’s a better product, just one with a lot more money on the line.
