My current BB levels: (ignore BBV)

Bismarck 75

Haruna Mutsu 54-57

Kongou Hiei Kirishima Nagato Littorio 33-40

Would it be better to aim at pushing all Kongou class to 60-ish first or Kaini haruna first? Surely levelling all of them to a relatively higher level first can reduce preboss retreat rate by a hopefully significant percent, but on the other hand Kainiing haruna do give extra luck, stats and equipments that would be helpful for final kill...
