It's not nearly as noticeable as people make out. I doubt that anyone could really tell the difference in a blind test. Compared to tires with protection built in, the difference would be even less noticeable.
Tire liners have the added advantage of cost. A Mr. Tuffy liner can last for decades...out lasting many sets of tires. Tires with integrated liners are a single use item. Once the tire is worn out, the liner is discarded with the tire.
