Flannel has a higher gram weight, which means its fabric will be thicker, but coral fleece is warmer, comfortable to cover, and easy to clean without deforming and pilling.
Flannel plush is fine, and coral plush is thick and sparse; therefore, coral plush is easy to shed, and flannel is easy to not shed.
The same pattern, coral fleece fabric will appear fuzzy, while flannel fabric will be clear and bright. From the price point of view, flannel is a new product and requires high craftsmanship, so the price is a little more expensive than coral fleece.
Coral fleece has small coral fleece-like particles on the front, while flannel has a smoother surface. This surface difference is more intuitively reflected in the feel of the two fabrics, and the surface of flannel is softer.
Summary: From the above difference between flannel and coral fleece, flannel fabric, as a new variety, is indeed better than coral fleece fabric. However, if it is a special coral fleece fabric, it is not inferior to flannel. When it comes to comparing the prices of the two, it's up to you which one you choose!
