Our overall assessment is that the "half-and-half" choice of 50% HF exchange behaves particularly well for problems that are known to be affected by SIE. As such, it is not happenstance that BH&H-LYP tends to find its most widespread utilization in TD-DFT calculations, and in ground-state applications where CT character is potentially an issue. Neither is it the case that BH&H-LYP simply benefits from being a "named" functional in standard quantum chemistry programs, which happens to have a large fraction of exact exchange. Rather, BH&H-LYP exhibits favorable performance even as compared to other B(α)LYP functionals with larger or smaller fractions of exact exchange. BH&H-LYP also outperforms the M06-HF functional, 148 which was designed with 100% HF exchange for spectroscopic (TD-DFT) applications.
