The results in table 5 and figure show two key trends-the general improvement in the performance of density functionals as one goes up the rungs of Jacob's Ladder, and the improvement of the results when dispersion corrections are applied-that match the findings of many other benchmark studies. The MMAD of each rung is lower than for the previous rung for both the plain and dispersion corrected functionals, and the improvements from higher rungs are visually obvious in the changes in shape seen in the violin plots. The density of the data narrows dramatically and the interquartile ranges get smaller. The ranges of deviations (the length of each plot) also decrease, but there are still long tails in the plots for the hybrids and double hybrids as some systems are particularly sensitive to the amount of Fock exchange or MP2 correlation in a functional. For all DFAs except revTPSS, both the DFT-D3 and DFT-D4 dispersion corrections either lower or do not change the MAD, so we recommend their use as a default. For further analysis on the effect of different dispersion corrections, see SI section 4.1.
