Go for ASDIC, since it's currently unobtainable otherwise right now. You can get a TBF or even 2, on the Saratoga quest.

The Swordfish has little use right now, but you'll have to choose between Shinden Kai2 or Swordfish, and you can build the Shinden Kai2, so pick the Swordfish (it might become upgradeable in the future, who knows).

The WG42 is pretty good to be honest, and helps a lot in events, Since it's less available than Daihatsu, unless you got no Aircraft Blueprints, get it. If you have no Aircraft BPs, go for the BP instead and farm Yuu in the next event.
