None of the AES finalists have been "broken", and all of them (except maybe I think Serpent?) have had cryptanalytic results published in the literature. It is indeed because AES is the standard --- everybody uses it, there are many good-quality implementations, and everybody knows how to use it.
It's all kind of a moot point. If you're typing the name of a cipher into your code, you're doing it wrong, and you'll pay down the road when you get pentested.
