GrapheneOS provides much better privacy than CalyxOS including features like Contact Scopes, Storage Scopes, per-app Sensors toggle, Network toggle instead of the leaky LineageOS approach, per-connection MAC randomization, fixes for many data leaks and much more.
GrapheneOS provides much broader app compatibility than CalyxOS via sandboxed Google Play. Apps forbidding using an alternate OS via the Play Integrity API is an issue for any alternate operating system and it's known that spoofing the device integrity check for Google certification is not a sustainable approach that will keep working. It already doesn't work consistently.
CalyxOS is not a hardened OS. It greatly reduces security vs. AOSP via added attack surface, rolled back security and slow patches.
Compatibility with Android apps on GrapheneOS is also much different. GrapheneOS provides our sandboxed Google Play compatibility layer:
Can run the vast majority of Play Store apps on GrapheneOS, but not CalyxOS with the problematic microG approach.
