Really anything other than FPTP is fine. RCV only has the same outcome as FPTP, where the least liked candidate can win, in ~10% of outcomes. Really we should be okay with promoting most of the alternatives since they can be modified down the line as well. I personally promoting Ranked Robin, STAR, and Score more but RCV is always worth supporting if it’s on your local ballot vs FPTP. Most people are just more familiar with RCV if they have heard of some of these alternatives.
