@Eòlach I'll probably just get Lineage on it. Way more trust in them since I've dealt with and slightly contributed to the project over the years Those two seem to clash and be riddled with dramas of some sort so I'd just do Lineage (which only connects to Google's NTP, not an issue for me.) and set up the thing myself
There doesn't seem to be much drama as far as CalyxOS goes. Just with the developer of Graphene who has since stepped away and is taking more of an advisory role on the project for the time being. At any rate, both come highly recommended so I'd encourage you to check them both out. I can't really speak to the privacy/reliability of Lineage in comparison to CalyxOS and GrapheneOS which have specifically been made/hardened for privacy.
