I suspect that the difference is in subtle and in the BOM.
A ten dollar difference could be as simple as heat sink
or capacitor thermal specifications. The heat sink could
be invisible -- i.e. more/ thicker copper on the logic board
Contract manufacturers may also bring better quality practices
to the table.
Different internal filters, bearing seal or lubrication specifications
may also apply. I doubt that firmware is different.
