When most people say "ranked choice" they seem to refer to IRV, which is broken in multiple ways, but most notably that it has the property that ranking someone higher can make them lose and ranking someone lower can make them win. That happens because IRV ignores all of someone's preferences except their top choice, until their top choice is thrown out, at which point IRV looks at their next preference.

There are much better systems: approval (for simplicity, at the expense of more accurate preference information) and Condorcet (for accuracy, at the expense of making it more difficult to explain tie-breaker corner cases to the average person).
