Models of natural supersymmetry give rise to a weak scale m_{weak}~m_{W,Z,h}~100 GeV without any (implausible) finetuning of independent contributions tothe weak scale. These models, which exhibit radiatively driven naturalness(RNS), are expected to arise from statistical analysis of the string landscapewherein large soft terms are favored, but subject to a not-too-large value ofthe derived weak scale in each pocket universe of the greater multiverse. Thestring landscape picture then predicts, using the Isajet SUSY spectra generatorIsasugra, a statistical peak at m_h~ 125 GeV with sparticles generally beyondcurrent LHC search limits. In this paper, we investigate how well theseconclusions hold up using other popular spectra generators: SOFTSUSY, SPHENOand SUSPECT (SSS). We built a computer code DEW4SLHA which operates on SUSY LesHouches Accord files to calculate the associated electroweak naturalnessmeasure \Delta_{EW}. The SSS generators tend to yield a Higgs mass peak~125-127 GeV with a superparticle mass spectra rather similar to that generatedby Isasugra. In an Appendix, we include loop corrections to \Delta_{EW} in amore standard notation.
