Similar but Beaglebones have flash drive controller which they boot off so they do better at not corrupting themselves on power cycling. I don't know about the BeagleY-AI but the Beaglebone black's power sequencer has won't fix issues that cause the board to fail to start if the power comes on too slow. Open source hardware means they give you schematics and the board layout as an Altium project. You can take that and customize it to fit your needs. When it comes to processors that can run embedded linux that's actually common. Advantage if you don't modify the layout of the high speed buses your prototype will likely just work.
