A standard complement of Poplestyle basis sets is tested, ranging in quality up to 6-311++G(3df,2pd). In modern electronic structure theory these are often regarded as low-quality basis sets yet they are still widely used, in part because certain quantum chemistry programs (including Q-Chem) have been optimized to take advantage the use of sp functions in Pople basis sets (i.e., s and p functions with a common exponent). If so, then Pople basis sets are considerably more efficient per unit basis function as compared to other alternatives. Karlsruhe (Ahlrichs) "def2" basis sets are also tested, up to quadruple-ζ quality, as are the correlation-consistent basis sets cc-pVXZ and aug-cc-pVXZ, for X = D, T, and Q.
