In TC, I think PnS has many advantages, and particularly on tight and high bite tracks. I agree that PnS may actually be an easier driving style. For example, if you purposely drive in hard you somewhat expect the car to get a little loose and are therefore ready for it. As opposed to a smoother style where you'd still like to drive on the edge, but the break-loose point is often a fine line and if it snaps can often lead to an undesired, and unexpected, situation. Touring cars have so much forward grip with all four (or at least three) tires pulling, that PnS can work well. The lateral grip is the problem on TCs, it's not forward grip. I personally drive smoother (I believe) than aggressive, but I often pay the price if I initiate a corner incorrectly. Pan car is a different story, especially single cell and higher turn motors where momentum is king.
I essentially just reiterated what you said, but in a much less elegant way.
