To add to the list of resources for comparing XC functionals, I have
found this recent review by Mardirossian and Head-Gordon to be quite
informative:
"Thirty years of density functional theory in computational chemistry:
an overview and extensive assessment of 200 density functionals"
N. Mardirossian and M. Head-Gordon, Molecular Physics, 2017
http://dx.doi.org/10.1080/00268976.2017.1333644
They compared 200 functionals against a very large set of reference data
(nearly 5000 data points). The functional compared include PBE, B3LYP
and their dispersion-corrected versions.
I hope this helps,
James
