What are the differences between a flax egg and a chia egg, and which one is more suitable for baking recipes?

The main difference between a flax egg and a chia egg is the source of the egg substitute - flax egg is made from ground flaxseeds, while chia egg is made from chia seeds. Both can be used as binding agents in baking recipes, but chia eggs tend to have a more neutral flavor and a smoother texture, making them more suitable for baking.
