As for the performance of the various methods, Petersson-type and Melius-type BACs show very similar performance, though Melius-type BACs appear to generalize better. Both approaches are a substantial improvement over just using AECs as previously noted in the literature. By comparison, the isodesmic reaction approach does not appear to offer marginal advantages over BACs. Therefore, we generally recommend using Melius-type BACs to obtain accurate enthalpies of formation due to its advantages, although using Peterssontype BACs should be viewed as almost equivalent, especially if the target species is well represented in the reference set. Last but not least, given the variance in both cost and performance across different QM levels of theory, there is a compelling need for a systematic review and benchmarking of enthalpies of formation calculated via LOTs frequently cited in thermochemical literature. Such an effort promises to offer profound insights, guiding researchers in choosing the most suitable LOT for specific chemical contexts, and advancing our progress in efficiently obtaining accurate thermochemical values for a wide variety of molecules.
