Has "ranked choice voting" been extensively studied in game theory? Is it the consensus that RCV is the voting system with the least number of drawbacks?
Range voting seems to have the least drawbacks from an actual political science view, but its complexity makes a hand counted audit rather challenging when you don't want to trust anything electronic with counting votes.
For that reason I prefer approval voting (as well as how simple it is to explain) but I'm happy to get behind any change that has momentum. We have the worst possible system right now, so any movement is good.
I've been in online discussion forums for over a decade with theory nerds discussing the merits of dozens of possible algorithms for counting votes and picking a winner. There are lots of known shortcomings and advantages and tradeoffs and there are some generally agreed on pretty-good solutions. Condorcet's election method is my current pick for what to advocate we actually enact.
