Comparing Graf Zeppelin, Wasp, and Shinano

Which was the worst carrier design: Graf Zeppelin, Wasp, or Shinano?

Graf Zeppelin was worst; Shinano's weaknesses were compounded by poor system familiarity, while Wasp was competently operated despite major design compromises.

Graf Zeppelin ranks last by a wide margin. Shinano may have been better than Wasp, but her complicated damage-control system was not fully understood by the officers and crew. Wasp benefited from a capable crew, yet the ship itself was built with compromises that limited its fitness for high-end carrier warfare. The comparison separates design quality from the training of the people operating each ship.
