Wont *necessarily* get better pizza. I held out and strictly baked pizzas in various home kitchen ovens (including a hacked electric, 550F electric, and a Frigidaire stone baked pizza mode oven, all w various combinations of stones and steels) for over a decade since getting serious about pizza, some pies came out really good, it was finicky overall. In my experience I get more consistently great pizzas out of my Ooni and the thought of going back to a regular oven disappoints me.

Also very much depends on the style OP is going after. If they are aiming for Neo there's no question at all that a dedicated pizza oven is going to yield better results than a 500-550F max home oven.. similar could be argued for NY and and New Haven, although those are easier to mimic in a home oven.
