The answer to this question depends on your needs and budget. If you're looking for an oven that can produce high-quality pizzas, then a wood or brick oven may be the best choice for you. However, if you're on a tight budget, a smaller oven may be cheaper. I can see what all the fuss is about.
The Ooni is worth the experience it offers. I say experience because I think that making and cooking food can really be an experience. There are firewood options that don't need gas or electricity. Even a decade ago, the only domestic pizza oven you could find was a permanent wood-burning pizza oven, the kind you see in real pizzerias.
In addition to the initial outlay, operating a pizza oven is economical and it's also extremely cheap to make pizza. It has a pizza stone inside that gives you that delicious and crunchy dough of a traditional wood-fired pizza oven. The 16 Koda offers you enough space to move the pizza and also a good distance between the pizza and the flame itself in case it starts to cook too quickly. If you plan to use your pizza oven frequently for outdoor meals and garden parties, regardless of the outside temperature, or if your pizza oven is very heavy, then a good quality weather resistant cover is your best option.
In fact, I have a raw wood burning pizza oven and a pellet smoker (Traeger). I ate a pizza in an Ooni oven.
