I guess this is really what I'm getting at. Is that statement always true? There is likely a crossover point beyond which diffraction obliterrates whatever additional detail you gain by increasing depth of field. On the other hand, if any amount of blur resulting from defocus always looks worse than any amount of fuzziness from diffraction, then I guess the statement would indeed always be true - meaning for sharper prints you are always better off decreasing the size of the CoC than maximizing resolution. Is this true?
