Papa John's pizza is just better.
It's the only chain that serves something that resembles an actual pizza.
Granted they're not the same everywhere, I've tried these things in over 5 countries, I used to eat pizzas 3-5 times a week and I think I'm qualified to make this assessment
Haven't ordered from a big chain in years, but if I do it's going to be Papa John's. Pizza Hut used to be great in the 90s and early 2000s but is close to sponge junk nowadays. Dominos' texure just drives me off.
Small pizza joints do a much better job. And some small local chains also.
Stock buying is not about how you feel, it's about what the majority does. I'd back Domino's stock if I didn't have the mentality of liking and understanding what the companies I invest in do. I like pizza, but not theirs. It's average at best.
