I agree about GrapheneOS - it’s the best (unless Google hardware is backdoored - does anyone check microchips with a microscope?).

Lineage OS / iodeOS / etc:

/e/OS is very beginner-friendly (as was Mandrake Linux from the same guy) compared to GrapheneOS, and it has been translated to more languages. My newest opinion about /e/OS after 1.5 years of use: https://piefed.social/post/2293825#comment_12563961
