IGES predates STEP and is still requested by older CAM systems and mould and die workflows. It stores exact geometry, but many IGES files are loose trimmed surfaces that never close into a watertight solid. Unless someone asks for IGES by name, STEP is the better choice.
A CAM programmer, toolmaker or legacy system asked for IGES, or you were handed one and need something current.
