Chopin trumps Mozart?

People always talk about Mozart as a great prodigy, composing and performing as he did from the age of 4 or 5.

But if you compare Chopin's earliest works, from about the age of 7, they are amazingly intricate and much harder than anything Mozart wrote as a lad. You can buy Alfred's publications of Chopin's earliest works and of his easiest works. The earliest are by no means easy, and many of the easier works are not the earliest works.

So far, I've not seen anything cleverer, written at such a young age from well known composers, but I'm happy to be corrected.
