The terminal guidance package on a modern Stinger is significantly more sophisticated than the Piorun, which uses a terminal guidance technology more in common with older Stinger variants. Modern Stingers use the same guidance package as the AIM-9X Sidewinder and have a dual mode IR/UV imager that is largely impervious to flares. There isn't anything more sophisticated on the market.
