which essentially punished the GOP Prog-haters for voting sincerely.  despite the (false) promise that they could vote for their favorite candidate without fear of helping elect their least favorite candidate.

well, if there **is** a CW, any Condorcet method will guarantee that the CW wins.
all of this differentiation between sincere CW and just CW is really too difficult because we cannot open people's cranium and peer inside
to see what their sincere vote is.  i think the only reasonable assumption is that, with sufficient *credible* assurance (that tactical voting will not help their political interest any more than sincere voting) that all ballots are sincerely marked.

of course, a Condorcet method will do better than any of those.  why bother with something non-Condorcet if the target is electing the CW?  i don't get it.
and direct comparisons cannot be made.  Approval collects too little data
compared to a Ranked Ballot and Score forces the voter to concoct and yield too much data.  it can only be compared if the ballot format is the same.  so different RCV methods can be direct compared.  but comparing methods with different ballots requires assumptions to be
made.

not "arbitrary" but incorrect.

and Ranked Pairs of Schulze allow an even better chance.
