2x46cm recon AP works out great on Yamato-class. The AP cut-in is 150% modifier which is enough to kill most things when you have capped out firepower. My Musashi often hits 200-300 with it. It has a pretty high proc rate. Double attacks generally do more damage against weaker ships. Against high armor ships like Re, the AP configuration tends to do more damage. Against boss ships that have high armor and hp, double attacks can be better since you can chip it twice.

BBV are pretty low in firepower so AP setup would probably be less efficient than double attacks.
