Just depends on what you want to do/what your customers will pay for. If everyone does pan, you could set yourself aside by doing screen pizza. But you may need to tweak your dough recipe to switch over to screen.
I have spent the majority of my pizza time with screens only. I have occasionally worked with pans and honestly i prefer screens. A lot less work and effort, and easier to maintain quality imo.
Not everyone/everywhere is the same. You could do a test with screens, just do like 1 batch at a time and just start with one or two sizes and see how it goes. You could also take the time to tweak your recipe until you find the perfect spot.
