That having been said if you don't have goat heads then the Schwalbe's are awesome tires, I really like my Marathon Winters. If you do have goat heads or a LOT of road debris the Armadillos are the way to go. They use a special kevlar weave from the others and have a wider band of protection, and normally beat out other brands in puncture resistance. They are not responsive and are a little slow, but it was a trade off I was willing to make since I was getting 4-5 flats a week.
