My husband has strongly resisted making pizza on the egg for unstated reasons. I finally talked him into a stone. I made cold fermented dough for the first time, got the egg up to 550-600, and cooked the best pizzas we have ever made. But I had two variables -- new dough and the egg -- so I couldn't make any conclusions. Yesterday, after the remaining dough had been in the fridge for three days, I cranked the oven to 550 and heated our old pizza tiles for a half hour. Made the same type of pizza, light sauce, pepperoni and moz. And they turned out just as good. Really. In the same amount of time. So in my view, the only reason to use the egg is if you don't want to heat up the kitchen.
