Losing a lv70+ ship = lots of time/resources wasted + 1% chance of getting Nimu (though you have 1 less ship to fight the boss so you have a higher chance of not getting S-rank)

Retreating = 10-15 mins of morale + 1 more bucket

Retreating is almost always the better choice. I also learned this the hard way by sinking a lv91 RJk2 at 4-3 (subs in echelon/abreast formation doesn't mean you're safe)
