I wonder how it compares to FR-2, an older paper-based PCB substrate. These new bio-based PCBs seem to have some characteristics closer to that than to regular FR-4.

Poorly. PLA has a notoriously low heat deflection temperature, losing nearly all yield strength above about 60ºC. Any 3D printing enthusiast will know that PLA turns into a wet noodle in a hot car. Unless they've made a significant breakthrough in polymer chemistry, this substrate just won't work for the vast majority of applications.
