I regard myself as a bit of a pizza snob, having built a wood-fired oven and making overnight Poolish or levain-based doughs which make most excellent pizzas.
But I'm going to disagree with the comments regarding the major commercial outlets.
Pizza covers a wide range of different things, and you can't compare them directly. Each has it's own time and place. I have time for Dominos, and I have time for Pizza Hut. Pizza Hut is a totally different thing: a Deep-pan pizza. It's not comparable to flat-baked pizza, and has it's own place in the ranks of dirty pizza.
Yes, I have a ranking for commercial pizza, and I think Pizza Express is a decent source of sustenance on an evening out, and on an audax. Dominos works for a short-notice arrival of a horde of hungry PSOs. Pizza hut, not been there for a long time now but as I say, a different thing which can have it's place and I would not refuse at need.
The common factor is that the tomato sauce is not so much sweet, but salty: heavily seasoned with garlic salt. This results in a 'pizza thirst' an hour or so later.
