question to all its drivers and all with nem lockdiff

hello, I have a point: I will hold a lecture about lock differentials in the context of my studies. but I have never driven a car with lock diff, so here, for example, the drivers of an itr (he has a frontal lock differential) could post their experiences against vehicles without lock diff (e.g. the German ctr). what about the attraction advantage on wet road, driving behaviour in curves and which parts have your opinion after lock diffs??? gruß edit: thx for all experience values
