STAR is ridiculously bad, it just has good marketing. It favors the preferences of voters who pick extremes, ranking everybody either a 1 or a 5 - likely the least informed and thoughtful voters - over voters who carefully weigh whether a candidate deserves 3 or 4 stars. Ranked choice is simple and effective, takes more granular voter preference into account, and provides runoff for each virtual round, rather than just the last. It also has a simple variant that works equally well for multi-seat elections.
