That does look pretty darn tasty.
I think it depends on how you like your pizza done and whether you want to make them from scratch or not. If you are okay with a melted top only or minimum color or medium crust, the SF will rock with proper preheating and a pizza stone as you have shown. If you want more browning on top without charring the crust, especially if it is cracker crust, you may want to google "The mighty pizza stone". It is basically an adjustable pizza stone to help control the stone temp. A stainless steel pizza grill cover helps to produce a darker top as well. The same guy who produced the adjustable pizza stone had a really nice stainless steel cover with a chimney and adjustable pizza stone on the top of the cover for sale. That worked really well, but it didn't allow my Summit (670) to close fully. It would be perfect for a large kettle, and I don't know how it would fit on the SF. Actually, I am not sure they even make the cover any longer, but there are others out there.
I gave up and bought a wood fire pizza oven last year from WPPO but the wonky door design has lead me to replacing it with an ooni-pro this year. For me it is efficiency as I make a LOT of pizza and flat breads over the summer with all the kids from the family over almost every weekend to use the pool. Best time of the year, though, outdoor cooking AND family!
