SAGA was built around analysis rather than map production, which is what separates it from QGIS. It is particularly strong on terrain: slope and curvature, catchment and flow accumulation, hydrological indices, visibility analysis, landform classification and solar radiation over a surface. It also carries modules for geostatistics, interpolation and image classification.
In practice many engineers never open it: its tools are available from inside the QGIS processing toolbox. That is the common way to use it, and anyone working in QGIS gets it for free.
