I need something that I have confidence in; other wise I am just looking where the front tire is about to roll. Schwalbe Marathon Plus give me piece of mind and I have been using them for so long that I cannot remember what it is like with any other tire. They do occasionally get punctures and for me it is always the same thing: the tiny wire pieces from blown-out truck tires. Always on the same type of road: a busy state highway with a paved shoulder. I blame surly long-haul truckers; overloaded, going too fast on hot summer days with under-inflated tires.
