only if there are only two options, for more options any rank-ordering system will be plagued by Arrow's and other impossibility theorems. quadratic voting uses cardinal preferences, which avoids some of those issues, and QV specifically has linear marginal cost of votes, which can be shown to be optimal in a very simplified mathematical model of voter preferences. but I don't want to evangelize QV too much here, it has enough proponents already and I'm not fully convinced that's is resilient to problems like collusion
