Two approaches to precise calculations of the Higgs mass $m_h$ and the Higgs mass spectrum\\ \vspace{2mm} -- fixed order (up to 3-loop) calculations of the complete diagram set in the "full" MSSM. Uses fixed-order evaluations of the renormalized self-energies in the Higgs propagator matrix.\\ Preferrable for low MSSM scale, where {\tt logs} $\sim$ power terms.\\ \vspace{2mm} -- resummation in the effective theories (EFT). Uses resummation of certain classes of diagrams in the zero external momentum approximation. MSSM particles decouple at $M_{SUSY}$ scale, are integrated out at the thresholds. Pole masses of scalars are evaluated for the two-doublet effective potential transformed to the mass basis. \\ Preferrable for high MSSM scales, where large {\tt logs} should be resummed. \vspace{2mm} Evaluations in our case\\ -- resummed effective one-loop two-doublet Higgs potential ($\overline MS$ scheme) in the generic mass basis\\ -- moderate $m_A$ scenario, rotation to the Higgs basis is not used for matching with the low-energy SM-like model at $m_A$ scale, so not specifically corrections to $m_h$ but full spectrum of $m_h$,$m_H$,$m_A$ and $m_{H^\pm}$ defines the mass basis.\\
