- We perform an extensive analysis of the light CP-even Higgs boson pole mass in the MSSM and its dependencies on various parameters based on the 3-loop FlexibleEFTHiggs hybrid calculation which is implemented and publicly avaiable since recently in FlexibleSUSY. Our focus lies on the study of the robustness of the approach in scenarios of highly non-degenerate SUSY mass spectra. Also, we present an improved Higgs mass calculation in the NMSSM based on the same approach, which is published in the new version 2.9.0 of FlexibleSUSY as well. The calculation provides a treatment in the full-model parametrization, leading to an advantageous resummation of QCD-enhanced terms in the stop-mixing parameter and includes important 2-loop contributions as well as 3-loop QCD contributions in the MSSM limit. We assess the reliability of this new calculation by applying it to several distinct NMSSM scenarios. In this context, special attention is devoted to the estimation of NMSSM-specific theory uncertainty.
