I think it depends a lot on the oven and the crust type you're making. I like a medium-thick but chewy type crust. The convection fan usage tend to dry things out faster, but doesn't brown as well as the straight "bake" setting does. Most commercial pizza is done in convection ovens, but at a very high heat.
Does yours have a fan or just a countertop oven? It looks really nice.
I can only go to approx. 450F in mine, I also got it used and don't have the baking pan it would've come with, just the racks and an old smaller pan, so I improvise.
I use a combo of both setting depending on toppings and thickness to get the results I want. I don't have an actual stone, but do have an 1892 Griswold 12" bail-handle griddle that is smooth as glass and works great as a 'stone', but takes some time to preheat.
I'm lazy, so I tend to cook 'em right on the rack, but using parchment paper to keep the bottom from being over done or sticking to the rack. Also works to allow me to move the pizza around if needed too without a proper paddle. If the bottom needs more heat to rise or brown and is cooked enough, I just pull the paper out.

Whatever works, I say!
