they have their own roles.. if you see it merely from a sum of night battle atk power, then yes, CA will be a better choice.. but there are some cases where you will be lacking a little fighter power coverage against the enemy that you would encounter within the map, you can use CAVs/BBVs to earn that little fighter power so you can get AS or AS+.. that's why i tend to use at least one aviation ships, most likely the fusou sisters kai ni, their armor and HP are bad, but they offer something a normal battleships don't which is their extra 14 fighter power..

as Vz-Rei said, they also give better LoS during event.. and sometimes for an easier routings.. take a good look at report and result thread of E-3's winter 2015 and E-5's spring 2015 .. they are good examples of why having CAVs are pretty handy for routings..
