The def2-TZVP basis set is recommended in Ref. 1 and its performance is within 0.5 kcal/mol of def2-QZVPD, but at the same time the error statistics for 6-311G(2df,p) are not much different, and indeed have smaller standard deviations with respect to the benchmarks. Statistics for 6-311+G(3df,2pd) and G3Large 47 are a bit better still. In Ref. 1, the median absolute deviation is used as the primary accuracy metric, as it greatly reduces the significance of any outliers, but it also provides less of a means to discriminate between basis sets as compared to a broader suite of statistics. In particular, 6-311+G(2df,p) reduces the standard deviation of the errors by 2 kcal/mol, relative to def2-TZVP, for the meta-generalized gradient approximations (mGGAs), a significant improvement that is not adequately reflected in the median absolute errors. In view of the full compendium of statistics, we see little reason to recommend def2-TZVP over 6-311G(2df,p).
