Give it a try (on both sides)!
No way a single side coated paper will have same image quality (sharpness and saturation) on both sides.
About the somehow different texture on the two sides, it is a unavoidable reality on thick papers made on Cylinder mould machines. As the pulp is caught by the cylinder to form the paper, the cylinder texture is imprinted on the back of the paper (the surface of the cylinder is actually a metal colander) while the front texture of the paper is determined by the type of fabric to which the pulp is transfered to. Later on the textures may be smoothed if the paper is hot pressed, but it will never be exactly the same on both sides.
Edit: Rag Photographique is not mould made, no mould cylinder. It is made on a Fourdrinier machine, but the idea is the same: one side gets the texture of the wire imprinted on it.
Best regards.
