A comparison is presented of the two methods mentioned in the title for treating hadron properties in QCD.While the general parametrization is derived exactly from real QCD,the equivalence of the large N(c) description to real QCD with 3 colors,is questionable.The reason why in some cases the large N(c) method approximately works (while in others does not) is clarified.
