I have a very small pool of Androids I consider. Pixels maintain a strong security model (similar to what iPhones have), and they allow you to re-lock the bootloader after installing a non-stock OS. It's between a Pixel, or a FairPhone.
I liked Lineage, but an unlocked bootloader is a security non-starter for a device that's so personal and vital.
For those using the stock OS, Googles are nice because you "only" have Google's spyware built in to the OS.
