The difference is, the Chitose Sisters can be used used as replacements for expeditions requiring CVs so it doesn't actually cost extra, while Akitsumaru doesn't fulfill any composition requirements, so is an additional cost to the other ships needed.

In any case though, their resupply costs make them impractical for short expeditions, so they're only worth bringing to 7 hour + expeditions
