Dennis Hanover, founder of Hisardut, came and taught us some grappling techniques during my instructors course. It uses a lot of grappling techniques, and is in that sense superior to krav maga on the technical level, since krav maga has virtually none. However, a lot of emphasis is placed on brute strength. Attacks to the head and groin are non-existent.
Dennis has been quoted saying that krav maga is the best style for practicality, more than his own hisardut, on more than one occasion.
