Bismarck and Tirpitz have to be the most overrated battleships in history. They were just an updated version of the World War I era Bayern class battleship. One problem with the ships was the lack of a dual purpose secondary battery. Weight and space were wasted on having to use two systems.
By 1940 only Air Craft carriers were capital ships. Thus of the Axis powers only Japan had capital ships.
Big part of the reason the Axis lost the war.
