Depends... Classic and really well made with nice ingredients then thin but also like they used to do old school deep pan at Pizza Hut in the 90's was so tasty...
I only ever eat pizza for the purpose of gorging on fast food therefore I don't see the point of eating thin crust pizza that isn't going to fill me up. Either go hard or go home.
If you like deep pan then try Chicago style. Like 5cm high and packed full of cheese, tomato, and meat. So good. Probably like 700 calories a slice; I've never managed more than two slices. Google search for it. Im on my phone otherwise I'd link to it. That's real deep pan.
