Fast Food Pizza has a few lacking qualities: One: Low Grade Cheese, and Dough that doesn't taste good.
For Little Ceasar's you get what you pay for, it's cheap, and it tastes cheap. I'm fine with that. They use canned mushrooms, and some of their meat toppings are also extremely cheap. For $5, you can't complain.
Pizza Hut is horrible. Their bread really feels like it has been grown in some lab. Their new hand tossed pizza still tastes like it came out of a box, and their pizza remains one of the most greasy pizza's I've ever seen. Bad looking and bad for you. On the plus side, their marinara sauce on their pizza isn't so bad. It's just the rest of the pizza I can't tolerate too much.
Papa John's cheese just doesn't taste right. There's something about the texture, the way it tastes once it's baked, doesn't taste at all like 100% Mozzarella. Maybe they use some weird blend? Their bread is too rubbery on the bottom, and tasteless & dry at the edges.
Domino's Pizza has improved, their bread has improved, and the toppings have improved. That being said, their cheese also does not taste right to me, almost as if it's been too mixed with other cheeses or possibly skim? Their bread is rubbery like Papa John's now. All that extra greasy 'flavor' they brush on the crush and bread doesn't mask the tasteless bread.

My preference in Pizza's over $10: Crispy bread (on the bottom and edges), not rubbery. Easy on the cheese, give us whole 100% mozzarella.
