To use your coined term, there is #Goolag baked into the system on either of those options being based on LineageOS.
DivestOS is the better of the two, they port GrapheneOS features listed here:

Then how much more open do you believe other OEMs are?
At least with Pixels and Graphene you get AOSP and the open source Trusty OS and Open Titan as the basis for the TEE and RISC-V secure element which is a lot further than most other phones.
Which vendors using those OS that aren't Pixels and with removable batteries provide up to date patching and security updates for their firmware/drivers to the same standard or better?
