We show that where standard criteria for model selection are decisive, the $\\alpha\\beta\\gamma$ model is favored over the special case of the Plummer model, and also over the \\sersic\\ model and its special case, the exponential. The Milky Way's dSph population exhibits a diverse range of stellar density profile shapes, as quantified by the values we infer for outer and inner power-law indices $\\beta$ and $\\gamma$.
