Without Kai 2, the Shou/Zuikaku are the worst CV of the bunch, while Hiryuu hits the hardest at shelling phase, while the kakus hit the weakest. Performance wise, no contest.

Hiryuu also gives unique planes at Kai 2, no contest again.

They are all quite rare, but Hiryuu can drop at 2-3, while the other two 4-4 or later. Unless you are lucky in construction and got them early, no contest yet again.

I wonder why are you asking such thing. The crane sisters are a disappointment as for now, despite historically they were more advanced and had some good contributions.

And before someone tells me I'm comparing kai 2 to kai, even as kai, they are weaker than these much easier to obtain Akagi and Kaga.
