Does it have a something like Apple’s Secure Enclave to protect cryptographic keys? Are apps strongly isolated?
Do you know what the anti-interdiction services are? I’m guessing that the each of the separate components are cryptographically paired so that third parties can’t replace the modem or touchscreen (for example).
AFAIK PinePhone Pro is still far from being a daily-driver-ready, so a comparison with it is almost irrelevant. It has no paid developers, so I don't expect it to be ready very soon.
Pine has a far more vibrant and treaded software ecosystem than Librem[0] at this point and many or most of the userland UI is using Purism's Phosh launcher anyway. Hell, if you want, you can build PureOS for the PinePhone too [1].
Pine has more real users with real devices and possibly more developers too since it's more Bazaar and less Cathedral in its approach to development.
You can have preferences, but this just reads like sour grapes.
It's pretty clear that you have never seen these devices next to each other - and that you never attempted to actually use the thing you posted instructions for.
There's a huge difference in maturity between PinePhone/Librem 5 and PinePhone Pro.
For me, the appeal of a Librem phone is less about security and more about ability to use the phone freely, e.g. filesystem access, ability to install my own software, and developing right on the device.
