dominos-thin
everywhere else-hand tossed (especially papa johns. they have the best dough)
never deep dish.
eta, i'm not the pickest person ever on pizza (yes, i'll even eat gasp gasp cicis!) but i've had very disgusting papa johns before. completely inedible. but i've also had very very good papa johns. some stores are definitely better than others. same for dominos and pizza hut.
