I've stayed with Aristos and don't regret it at all. Granted I run shorter trains for the most part, but I even put Aristo couplers on my USA streamliner set. There is a negative to Kadees, if your trackwork has any horizontal kinks (quick changes in grade) the kadees have a tendency to bypass each other when one rises while the other stays at the same level or drops. This is just what I've noticed on my own layout.
