Let's face it, unfortunately the GrapheneOS developer team depending exclusively on Google hardware is a terrible thing in the long run, I bet that overnight Google will close the siege with the Pixels or possibly even abandon them so the whole community will have no alternative
Google may also abandon Android, and there is no guarantee that another major company would keep it. I have real concerns about the Android model
PS: I know the hardware requirements that GrapheneOS has to support a device
LineageOS sucks at security, weakens Android's security model, doesn't deliver full security patches, to name a few of the problems. Better an updated iPhone and save your files locally than switching to Lineage
PS: I know I'll get a lot of hates for saying that but I'm being honest
