It depends on what you want to cook and your personal preferences.
A pizza oven is specifically designed to cook pizzas at high temperatures, resulting in a crispy crust and perfectly melted cheese. It can also be used to bake bread, roast vegetables, and cook other dishes that require high heat. However, it may not be as versatile as a BBQ, which can be used to grill, smoke, and roast a variety of meats, vegetables, and fruits.
On the other hand, a BBQ is great for outdoor cooking and can provide a smoky flavor to food. It can also be used to cook a variety of dishes, including burgers, steaks, chicken, fish, and vegetables. However, it may not be able to achieve the high temperatures needed for making pizzas.
Ultimately, the choice between a pizza oven and a BBQ depends on your cooking needs and preferences. If you love making pizzas and want a crispy crust, a pizza oven may be the better option. If you prefer a variety of outdoor cooking options, a BBQ may be the way to go
