I wouldn't have built them. The Germans as underdogs as naval powers go had two realistic choices on building a navy:

1. Build a coastal defense fleet and use commerce raiding as their offensive strategy.

2. Build a fleet around a core of ships that changes the current paradigim of what constitutes naval strength.

In WW 1 the Germans did the second by accident. With the advent of technologies that came together to change the nature of battleships... that is the construction of Dreadnought type battleships ..... earlier slow battleships were rendered obsolesent overnight. This allowed the Germans to start an arms race as a naval power against Britain from a position of essentially equality.
During the war the Germans failed to appreciably use their fleet against the British enmasse. With the exception of Jutland they never really fully challenged British control of the seas. At the time Germany could afford to lose their fleet; Britain couldn't.

By WW 2 the available choice in this area is that Germany opts for a carrier centered navy. This would have taken some really forward thinking admirals on the German's part. But, the ones they had were generally very conservative and hidebound in their views of naval operations. Hence they opted for battleships that proved very nearly useless.
