I think it's a fairly simplistic look at things, designed to make their own method look better. There's also at least one obvious falsehood there. In the spoilers section it claims that RCV (IRV) passes Independence of Irrelevant Alternatives. It certainly does not.

FairVote claims that "RCV" doesn't have a spoiler problem. It most blatantly does.

FairVote claims that your ballot will help your 2nd choice if your 1st choice doesn't win. False, & FairVote knows that.

FairVote says that it isn't known whether Condorcet has a spoiler-problem.

No, actually MinMax(wv), & then Smith//MinMa(wv) were introduced 35 years ago, & their strategy-properties were well studied & well-known at the time. It was known even then, that the wv Condorcet methods, which also include Schuilze & RP(wv) meet Minimal-Defense, & that truncation by only one faction can't take the win from a CW.

Those things have been well known among Condorcetists for 35 years. No, Condorcet(wv) doesn't have a spoiler problem,

But FairVote has a dishonesty problem.
