Kitahara has a point about additional firepower with FBB in second fleet. That being said, every boss kill for me has had a sub. I'd break it down into two choices:

A)   Full power!  Damn the consequences!  Maximum firepower for finally killing the boss, beating the map.  If you're doing this, go FBB.  I didn't, but I think Kitahara has the right idea.  If you're going all in on the map, then just ignore the maelstrom drain and sortie your support expeditions.  Burn her down.

B) The boss has been defeated, but you're trying to get Asashimo from boss prenodes, or you're hoping against hope for Isokaze (on normal/hard difficulty only) at boss.  This is where I'd start leaning towards the sub.  You've already gotten your kill.  Now, you're more interested in conserving what you can, and getting S rank in pre-boss nodes without going to night battle.  This is where a sub's opening and closing torpedo spread would be better than a FBB's single artillery strike.  Most of the time Goya will take out a destroyer, allowing your first fleet to pound heavier targets more efficiently, and her torpedo attack, combined with the CLTs, can really help wipe up what's left.
