Raising Bismarck for forensic engineering

Which sunken warship would be most useful to raise for a close study of its design?

Bismarck, because forensic inspection could clarify how its many design compromises and inefficiencies worked in the built ship; Yamato would also be valuable.

Bismarck is the preferred candidate because direct physical inspection could expose how its design compromises and inefficiencies worked in the completed ship. The aim is a forensic engineering study of the vessel's construction and design decisions. Hood provides a comparison: its plans and contacts with people connected to its designers have already made a detailed examination possible. Yamato is another candidate because its design also involved substantial compromises that would reward closer inspection.
