As I understood it, the German Navy paid more attention to each individual ship and followed the philosophy that as they could never have as many ships as the mighty Royal Navy, the ships they actually had should have an edge wherever possible. The idea behind the High Seas Fleet was to be a serious threat, at least, to the British Empire while being superior to every other navy. That way, it was hoped, a confrontation could be avoided, as the Britains would think twice before deciding against such an enemy.
Therefore, the German ships tended to get more attention and money than their British counterparts and had a few advantages on their side - it is said that a German capital ship cost about 30% more money than a comparable RN ship. They were generally better constructed and, in some respects, could take a great deal more damage. Underwater protection was particularly well developed, as it was thought the first job of a ship was to swim and the lessons from the Russo-Japanese War in terms of mine warfare had not gone unnoticed. For example, Goeben took more than one mine hit on its campaign in the Black Sea and survived several when making her sortie into the Med, she reached home in time to run aground on shallows and survived. Ships of the König and Bayern class survived mine hits in the Baltic without much fuss, as it seems.
On the other hand, of course, the German battle fleet had only one real theatre of operations, other than the RN, which had to cover the whole world. This is one reason for the superiority of the German battlecruiser concept: they were more a sort of light, fast battleship, as they could allow for more machine power and armour - they were not designed for long cruises, like their counterparts had to be in order to protect a globe-spanning empire. Likewise, the RN was much, much larger and forced to go in for bigger mass if they wanted to keep ahead of the game. But then, this strategy paid off and England continued to rule the waves more or less unchallenged, as long as the enemies stuck to the rules, that is - until the dawn of submarine warfare.
