One would think the line levels should be the same
The connectors (TRS and XLR) share the same differential amplifier, so there should be no difference in using either jack on the BFD. The shorting of the minus (-) input to ground of the differential amp raises the gain by 6dB to account for the unbalanced usage.

In fact, the 'quasi-balanced' configuration you reference that mississippi used is fine for reducing hum (if it's a problem), but suffers from not engaging the 6dB gain function.

If you aren't experiencing any hum problems, I would probably just use the RCA to TS plug, since that seems to work fine in your case.
