From all plots, it is evident that the choice of gauge is less important than the choice of basis set and method. However, Figure shows that the LG(OI) results converge faster than MVG to the CBS limit for all methods, especially for CCSD. Considering that LG(OI) is computationally cheaper than MVG and that it is less difficult to implement than LG with GIAOs for DFT, this choice of gauge may be optimal for OR calculations.
