even when tallying is perfect, i think #ApprovalVoting is usually superior to #RankedChoice for single-winner elections.
but i usually think the critique that #rcv is "complicated to implement" is a bit of a strawman (although "complicated to understand" is an important critique).
sometimes, however, the strawman rises from the haystack.
