Could you specify what you’re trying to do?

Normal LineageOS has integrated MicroG support, you can install it via the official MicroG F-Droid repository.

I can tell you that LineageOS is definitely good when it comes to security and data protection practices, but GrapheneOS is miles ahead by comparison due to its security preview releases and extensive hardening; LineageOS only applies monthly security patches once they’re released, and it makes good efforts to fix security vulnerabilities itself, like the VPN leak over QUIC, which Google refused to fix.

I don’t know much about /e/OS, but I personally wouldn’t recommend it if it doesn’t have anything you need. I don’t know of any security or data protection benefits it would offer over normal LineageOS. IodéOS, another LOS fork, does have some benefits, but it’s often far behind LineageOS when it comes to monthly security patches, which is concerning. I would therefore recommend sticking with LOS.

GrapheneOS and LineageOS are personally my favourite Android distributions.

“Custom ROM” is technically a false term for them, and LineageOS, PrivacyGuides and other institutions use the term “Android distributions” instead.
