Gas, electric and multi-fuel. Peak stone temperature sells the oven. How fast the stone recovers between bakes decides the second pizza, and it is published far less often.
What actually decides this purchase
Stone recovery, not peak temperature
Nearly every oven in this category reaches a peak temperature high enough for Neapolitan pizza. Launching a pizza pulls heat out of the stone, and how fast that heat comes back decides whether the second and third pizzas cook like the first. Peak temperature is on every box. Recovery time is on almost none of them.
Fuel, and how much attention it wants
Gas is a dial and a consistent flame. Wood and charcoal give you flavour and a fire to manage while you are also launching and turning pizzas. Multi-fuel ovens do both, usually with a burner sold separately. Decide how much of your attention the fire gets before you decide on a model.
Opening width against the pizza you want to make
A 12 inch oven makes 12 inch pizzas, and turning one inside a small opening with a peel is a real skill. A wider oven is more forgiving to learn in and needs more space, more fuel and more storage. This is a bigger practical difference than the size figures suggest.
These ovens run extremely hot and need clearance on every side and above. Work out where it will actually stand and what is over it, because a table under a low pergola is not a location.

BIG HORN 12" Gas Pizza Oven
Propane
A 12 inch propane pizza oven. A stone and a flame with no ecosystem around them.
A covered grill with a stone in it will make good pizza, and it will not make Neapolitan pizza. The difference is top heat. A dedicated oven puts flame across the roof so the top cooks in the same sixty seconds the base does. A grill cooks the base fast and the top slowly, which gives you a crisp bottom and a pale top. If that trade is fine with you, you already own the equipment.
Gas or wood?
Gas if you want to cook pizza. Wood if you want to cook pizza over a fire and consider that part of the point. Gas holds a steady temperature with a dial and is far easier when you are making ten pizzas for other people. Wood gives flavour and a live fire to manage at the same time as launching and turning, which is a lot happening at once for a beginner.
How long does one take to heat up?
Most gas ovens in this class reach cooking temperature in roughly fifteen to twenty five minutes, and manufacturers publish that figure. What they publish it against is the peak air temperature, not a fully saturated stone. Giving the stone another ten minutes after the oven says it is ready is the most common piece of advice from people who own one, and it costs nothing to follow.
