Personally I am not sure what "replacement for google captured android" means. That said, if you aren't using a pixel, you aren't using graphene. If you do have a pixel, then graphene is the way to go.

I find it easier to install, and the fact that you can run google play services in a sandbox, is a great safety blanket.

I just don't want to be spied on console or at least try to keep it to a minimum
