The results of this study support the commonly held idea that ascending the "Jacob's Ladder" of increasing DFT complexity will lead to improved performance: in general, hybrid DFT functionals performed better than non-hybrid/"pure" DFT functionals, and meta-GGA functionals performed better than GGA functionals among both pure and hybrid functionals. Nevertheless, the bestperforming pure meta-GGA functionals-r2SCAN, M06-L, and B97M-D4-all performed about as well as common hybrid functionals like M06-2X, B3LYP, and PBE0, demonstrating that pure functionals can give good performance where hybrid DFT is impossible or impractically slow.
