All round ropes will cut through the PVC. The braided rope is an improvement over the twisted rope, but it will still cut under high tension and long pulls. Also the use of the twisted rope with tuggers is a safety issue. It has too much stretch and can cause injury or damage. The braided rope is a more "static" rope and does not have as much stretch.
Some use "mule" tape to pull in PVC. It is flat and reduces the cut through.
