[gmx-users] g_energy for comparing total energies of 2 similar systems

I have two systems: 1. metal ion in water with a counter ion present in the bulk & 2. Exactly same system (with same no. of atoms as the previous one) with counter ion present in metal's first solvation shell.
Will it be fair to compare the total energies of both the systems obtained after production run using g_energy? Can we say the one with higher negative values is the more stable state?
Also, is it better to compare energies obtained using g_energy without any extra flag or the estimated free energy using the flag -fee in the g_energy command?
