Diesels do spin more freely because they have no throttle. So coasting in gear may be a good idea, particularly if a little engine braking is needed anyway. But, another advantage diesels have is they use virtually no fuel at idle, so, if max coasting is desirable and you are not comfortable with EOCing, you are better off dropping it into neutral and coasting engine on.
