I like both. If I teach a student to always 'attack' correctly, I could be missing stuff. So for a wrist grab, if they grab appropriately, X technique may be effective. But then they grab with their arm twisted around, and now all of a sudden breaking their structure looks slightly different. A lot easier probably, but it could confuse me if I expect the technique to work. With new people, I like to get a chance to work with them before they are taught to fight properly, so I can see more directly how what I'm doing would apply to an untrained person.
