I think the less training and/or currency in instrument flying a pilot has, the more he is going to find an artificial horizon to work better for him than some sort of turn rate indicator.

The inputs required to break a well-developed pitch phugoid without the aid of an artificial horizon, are counterintuitive.

But most important lesson that the pilot must learn is that must be prepared to utterly and completely believe the instrument, against what his senses are telling him. He must expect to be disoriented. I don't think it takes all that much training to deliver that lesson, so long as the training is truly effective. Which probably means, conducted in actual cloud!

Flying "partial panel", in my experience it's normal to be disoriented much of the time. Maybe this would no longer be the case if I had more practice at it.
