FWIW: I can't attest to any other tire manufacturer but I can say that I have been using Conti Gatorskins since Jan, 2011. Over 70,000 road miles total with only three flats caused by punctures. I've had more flats from valves going bad than punctures. I know that there are other tires on the market that can/will give the same performance, but since I've only used Gatorskins on my road bikes, I can't tell you which one(s) they are.
