I expect the rankings would be too subjective for credibility. - Edit 1

Like, get an average of the more rigorous/sensibly-sourced rankings of Presidents. See which voting record, the popular vote or the electoral vote, has the least amount of error were we to try to use them to reproduce that ranking. Hmm, but that doesn't work because the electoral college has loyalties to the popular vote on a state-by-state basis.
Though not because of the "vast left-wing conspiracy" below referenced. Ranking the presidents is just inherently subjective, influenced by proximity as much as partisanship. And, yes, with rare exception, the electoral college just amplifies the popular vote so Lincoln, Wilson, Clinton etc. get the majority constitutionally required.
