>I choose to believe that steel has higher peak achievable compliance but I have no proof
From what I believe, steel has higher stiffness before yielding while carbon has a higher strength to weight Ratio because it has higher ultimate tensile strength which allows carbon to compensate by using more material. This stiffness at the lower end of the stress-strain curve allows steel to be formed into thinner shapes which can bend without experiencing plastic deformation.
