for my money: t1 thru t3 don't really care. ...I feel like I'm slumming in those tiers. ...
T7 tough call...but it's the Minsk because like all the Russians, it goes hell bent for leather--48kts in the video breeze with the Sierra Mikes up and the boost, and those quick torps will definitely eff u up if i survive long enough to get within 4km...and the guns reload quickly.
T8 Kagero, but Benson is razor-close. ...more people like the Benson for it's versatility but I do better in the Kag.
T9 I've never had a t9 I enjoyed, now sure why.
T10 Shimakze ...I hear tell about the old Shima, but even the way it is now it kills. ...15 torps at 70kts, no waiting. ...and it's the only IJN DD whose guns aren't purely decorative.
Just for the record. He asked for the best, not the worst DDs of each tier.
