What are the benefits of Ceylon cinnamon over Chinese cinnamon?

I have read that Ceylon cinnamon is sweeter. It is also 3X the price. Is it really worth it?

The different types of cinnamon are the bark from different types of trees (of the same genus), so naturally, the flavour is a bit different. Which type of cinnamon is more traditional for a particular dish depends on which type of tree grows in that region. It's not so much a case of one being better than the other, but that one might suit the recipe you're preparing better than the other.

Almost all cinnamon available in North America is the "Cassia" cinnamon and it has a spicier flavour, is a darker colour, and when sold in sticks is thick, hard, and forms a loose double-roll shape. "True" cinnamon from Sri Lanka is milder, has a lighter colour, and when sold in sticks is more papery, brittle, and forms a tight single spiral shape.
