# Relative Energies of Resonance Contributors & Stability of Borazine

We know that Borazine (Inorganic Benzene) is aromatic in nature. The following image shows the resonance contributors of borazine:

What are the relative energies of these three resonance contributors? I know the last two structures have the same stability as they are equivalent, but I am unable to compare them and the first structure.

We know that aromatic compounds in organic chemistry have increased stability. Can we expect the same here? I am confused on this fact, as the second and third structures in the above diagram, have charge separation in addition to conjugated $$\pi$$ bonding.
