Shivans can use any node they want, I think that's all 
Well, obviously the Shivans could use nodes that the GTVA considered too unstable for use, so yes the Shivans did have better subspace drives, but I don't think they could use collapsed nodes, and I bet there would be nodes considered too unstable even for standard Shivan craft to use.
Giving the Lucifer an extra level of technology (the ability to stablise collapsed, or otherwise unusable, nodes) over the rest of the Shivan fleet makes sense, it can be used to help explain why the Lucifer appears to be rare (such technology could be difficult even for Shivans to build), and perhaps gives us an alternative reason for the behaviour of the Shivans after the Lucifer was destroyed.
The Lucifer was clearly an important ship for the Shivan fleet. After its destruction, the Shivan fleet scattered and was destroyed easily, not only had they lost their command ship and most powerful vessel, but they were also unable to return home without the Lucifer drive to stablise particular subspace nodes.
Anyway, this is just my humble opinion. Feel free to blast my reasoning out of the water.
