That is very interesting and I hadn't seen it before. IRV still does better than plurality by quite a bit, although it doesn't do well compared to the rest. As the chart shows, one of the biggest outliers is 100% honest voting with plurality.
I hadn't heard of 3-2-1 voting before but that is interesting. Maybe it would be one of the best. I generally prefer ranking to scoring (I'm not sure how much better someone prefers a candidate should really be part of the process) but the simpler tallying and presentation of results is nice. I also like that in the "scenereo type" breakdown the easy case gets the best results, condorcet cycles get the worst results, and the rest are in the middle (all with little effect of strategy). It seems like the right distribution to me, but none of the other methods measured get that distribution. IMO a ranked preference is usually much easier to determine how to vote (although it can still be an issue when some candidates are much closer than others), although I guess the limited effect of strategic voting should hopefully mean that it usualy doesn't make much difference exactly how you vote. OTOH, at least the names of the options should be changed; it is the rare race where I could describe any of the candidates as anything other than "bad".

IMO, proportional representation would be a much better change of voting system rather than just changing the method. Voting for one person is almost always going to leave lots of people unrepresented.
