I don't eat pizza often but when I do it's always Pappa Murphy's! The prices are great and their pizza is some of the best in town. At first I was reluctant to try it but my GF kept badgering me.
IME pizza comes out a lot better in a restaurant because they have the correct type of oven, but Pappa Murphy's gets around this by selling their pies on a special pan that really helps crisp up the crust.
Two thumbs way up, haven't had any other brand in over a year!
