IJN has mid-good range and damage (Yamato has great damage) with incredibly long hangtime. When played defensively and oin 1v1 (baiting/kiting), IJN excels, although this can be debated. IJN can slingshot pretty effectively, provided you are able to predict your opponent's whereabouts in ~5 sec. Rushing with IJN takes more time to master although it can be done, especially since some won't see it coming and will overshoot you.
All in all, it depends on your playstyle.
