From a comparison among the goodness-of-fit ($\chi^2$), unbiasedness of cosmological parameters (FoB), and figure-of-merit (FoM), we find that a four-parameter model (linear, quadratic, cubic non-local bias, and constant shot-noise) with fixed quadratic tidal bias provides a robust modelling choice for the auto power spectrum of the three samples, up to $k_{\rm max}=0. 3\, h\,\mathrm{Mpc}^{-1}$ and for an effective volume of $6\, h^{-3}\,\mathrm{Gpc}^3$.
