GrapheneOShttps://eylenburg.github.io/android_comparison.htm is a third party comparison between different alternate mobile operating systems. It could include many more privacy/security features but it's a good starting point.
Their services are also not private and are far worse than the services from Apple with end-to-end encryption support.
/e/OS and Murena are putting people in danger not providing the most basic aspects of privacy and security. It's just a lot of false marketing to sell products.
