As a new player I must say that from all of the available <T5 DDs (didn't go beyond that yet), the Japanese line is the least fun to play with for me. In fact I sold my Isokaze after giving it a last chance today.
Playing them is like pulling teeth, not really something I like to do in my spare time. I'm not even interested in grinding them to see if it gets better, the other lines are just more interesting to play.
