I'd plug the MOH into the Juice Bar. Unlike the wall sockets, the Juice Bar's sockets are isolated from each another. You'll supposedly get less noise and interference from adjacent sockets.
By the way, the Juice Bar is only a power strip, not a surge suppressor, right? And it has no power conditioning or regenerating circuitry, as I recall. If so, then you might want to get a surge suppressor or a power conditioner, just to prevent poor performance from dirty power, or damage from spikes or brownouts.
