If you want a good all-weather minimal maintenance chain, get a KMC Eco ProTeq rustbuster. I can get a full year of rain, snow, slush, salt riding out of a chain on my foul-weather / winter bike (usually at least 3000 miles on this particular bike, replacing around .5% elongation). I clean and relube with FinishLine dry lube about every 100-150 miles, adding additional lube as needed after getting soaked in wet conditions. I have never experienced any rust whatsoever with this chain.
With a similar cleaning/lube routine on a standard chain, I would experience rusted links and shifting problems frequently on winter commutes.
