The sonar spotting distance of a ship is based on that ship's FCS SPACE not what type of FCS you have. Then that base spotting distance is increased as a function of the true sonar ability of a sonar sailor (if onboard). DD and FF have auto sonar but the small FCS space means that FF are almost useless at sub spotting.
To have a real chance of spotting subs outside of torping range, you need a dd with big FCS (like Akitsuki-Kai) or a CL and a sonar operator.
So if you are worried about subs, FCS type is irrelevant.
If you are playing TW in blitz then FCS type is important because in the new Hobbit map world there are zillions of torps whizzing around and if you take the SS FCS to get speed by trading off ship and torp spotting distance sometimes you might sail into a sea of torps as you fffictory ahead of your team. That being said, with Sima speed is everything and you should be able to avoid torps even with short warning. With Kita, speed is everything, same advice. Take the SS FCS.
