Why is star grounding better than a D∗∗∗∗∗r style ground bus? The
circuit
topologies are equivalent, it seems to me (the MOTM power distribution
board being analogous to the ground bus).

I'm sure Paul can and will answer this, but as I understand it:
Equal length paths from termination points to the power supply =
Equal resistance from power termination points to the power supply =
Equal voltage drop at each termination ground (assuming roughly equal
current return on each ground) =
No voltage difference between ground points =
Lowest hum and noise.
Or something like that.
