Armadillos are one of the most puncture resistant tires out there. Almost anything is going to ride better than them (except the Schwalbe Marathon Plus which are even tougher.) Touring tires are a good option since they generally offer good to great protection. I had good luck with Gator Hardshells which come in 700x32. IME, any tire with good puncture resistance is not going to be as supple as an unprotected tire. Some people also buy a supple tire and install a tire liner but I've never done it due to the possibility of the tire liner chaffing the tube and causing a flat.
