  We present results on the analysis of the ratio of branching ratios
$R=BR(H->b\bar{b})/BR(H->\tau^+\tau^-)$ of Higgs boson decays as a discriminant
quantity between supersymmetric and non-supersymmetric models. A detailed
analysis in the effective Lagrangian approach shows how one could discriminate
between models at the Large Hadron Collider and the $e^+e^-$ Linear Collider at
500 GeV center of mass energy.
