The ballot is the same for all ranked voting methods. The method of determining winner from those ballots varies, and some are clearly worse.
For instance, if a candidate would beat all others 1-on-1 (Condorcet winner), then should a decent method always select that candidate as winner? RCV doesn’t do that.
Example
- A > B > C: 2
- C > B > A: 2
- B > C > A: 1
Who wins according to instant run-off? C. Who wins against every opponent 1-on-1? B.
This nice table compares voting methods by a wide range of properties. I don’t think it hurts to make a more informed decision before backing a method that will be difficult to change. The US got stuck with FPTP through inadequate research, and it’d be great not to repeat that mistake.
While rated voting methods fail the Condorcet winner criterion, by rating instead of ranking candidates they satisfy another set of criteria also worth considering.
Among ranked voting methods, ranked pairs seems most compelling to me. Among rated voting methods, approval seems pretty good (and extremely simple).
I think you missed the first sentence I wrote:
Maybe explaining what you think that means would clear up confusion?
Yes, approval voting is indeed susceptible to strategies including burial, which leads to a “chicken dilemma”.
