Many ways to skin a cat, and all (or most) will work just fine, pick the one you're comfy with. In the house oven, I use parchment. It may be $4 for 150' at Sam's, but I can cook 100+ pizza's with it. In the wood fired oven outside, I just smear a little flour on my dry wooden peel. Before I place the pie in the oven, I'll pull a small section up at the rear of the peel and blow under it. Since doing this, I've not had an issue with the pie sliding off, all toppings in tact. Another option is a cast iron skillet/deep dish pizza pan for regular pizza and chicago style and glass baking dishes for sicilian style pizza. Lots of options, good luck!
