I learned only yesterday that Google is going to effectively shut down open android. So I'm gonna have to move away from there. But what are my options? Is there a nice website that lists and compares alternatives?

I hear that Graphene is the goat, but I'm not on a pixel phone. Currently I'm on a Samsung galaxy a15

I hear about lineageOS as a good second, but it sounds like Google's decision to close down android might affect lineage too.

I hear about others, but I'm not too well versed in running obscure OS.
