We had a water softener growing up. My current city has ordinances banning them (something about it adding salinity to the drinking water). I never knew water spots were such a major issue until we moved here. We're talking you need straight up vinegar to get them off, and even then it takes some serious work. We have to squeegee the shower every use to avoid them.
In summary, I'm a firm believer in water softeners.
