Exterior Wall Construction Layers

Is 2×6 framing stronger than 2×4?
The total bearing area of three 2x4s is 15 3/4 square inches; two 2x6s have a bearing area of 16 square inches. In bending, however, such as from a wind load, a 2×6 wall is considerably stronger. In tall walls, where column buckling might be a factor, a 2×6 wall would be stronger if a structural sheathing was used.
