Returning to the overall results presented here, we remind the reader that popularity is not necessarily a good indicator of robust performance. Ranking the DFAs, each in its best (dispersion corrected) form, B2PLYP-D3(BJ) is 15th out of 17 double hybrids, while the Minnesota functionals M06-D4 and M062X-D4 are 7th and 10th out of the 15 hybrids, respectively. M06 and M062X were developed simultaneously, but the fitting set for M06 contained an additional database of transition metal bond energies 136 so it is generally better for organometallic systems. B3LYParguably the most popular hybrid DFA for molecular quantum chemistry-is regularly used for mechanistic studies of metalloenzymes, often uncorrected or with the older DFT-D2 191 or -D3(0) dispersion corrections. B3LYP-D3(BJ), however, only comes in 12th place, and is outperformed by the best functional in the rung below [MN15-L-D3(0)]. B3LYP* (B3LYP with 15% Fock exchange instead of the standard 20%) is sometimes recommended instead for metalloenzyme energetics, but here it is slightly worse: B3LYP*-D3(BJ) comes in 13th place, with its MAD 0.4 kcal/mol higher than B3LYP-D3(BJ). However we do note that use of the older DFT-D3(0) correction does not make the results any worse; data for B3LYP-D3(0) and B3LYP*-D3(0) are additionally provided in the SI.
