The following is taken from*CFD ISRAEL*blog (thoughts of a CFD blogger), addressing a branch of Scale Resolving Simulation known as 2nd generation URANS.
The specific SAS model is a*2-equation*unsteady RANS model, able to get very good quantitative results for many unsteady flows even on a relatively coarse mesh.

Scale Adaptive Simulation (SAS) – cutting on your computational budget in an unsteady*manner - CFD ISRAEL blog

Florian Menter's k-ω SST is one of the most reliable and trusted RANS two-equation eddy-viscosity turbulence models for the simulation of attached boundary-layer flows with adverse pressure gradient, and also serves as first choice for hybrid RANS-LES DES by many.

The following taken from CFD ISRAEL blog (thoughts of a CFD blogger) is intended to give a short and thorough review of the main reasons for the k-ω SST*Model popularity.
