Certification generation. The RZ-70S is Snell SA2025-rated; the RZ-70E is rated to the older Snell SA2020 standard. The shell material, ventilation, HANS inserts, and communication readiness are otherwise identical. The main practical differences are shield-series and cheek pad/crown liner part numbers, which aren't interchangeable between the two models.
