Range voting is superior to any other voting system in terms of how accurately the final result represents the wishes of individual voters.
RV seems to be the perfect voting system, meeting all the criteria which the Gibbard–Satterthwaite theorem (GS) says cannot all be met by a single system. The reason for this is that GS only applies to rank-order-ballot voting systems. RV does not depend on rank or order. (See also A Quantitative Version of the Gibbard-Satterthwaite theorem for Three Alternatives.)
