Create your own category with its own slogan. If you choose to compare with Domino’s then in the customer’s mind whenever they want pizza their choice would be between Domino’s and yours - it’s either Domino’s pizza or Your pizza. You’re both competing for the same space within the customer’s mind.
That’s fine if you’re competing directly with Dominos in terms of price and quality.
Although, if you want to dominate your pizza market you need to create a new “category” (an inhabited space in the customer’s mind) for your pizza e.g. “The best airy pizza, guaranteed” Now you’ve created a new space (a new category) within the customer’s mind, that you can dominate.
I recommend not going head to head with any established brands like PapaJohns, Pizza Hut, Domino’s but instead establish yourself based on, say, quality; type of pizza; price; or customer service - and wrap your slogan around whatever feature you choose.
Don’t worry about competition; worry about what your customers like and design your business around it, including your slogan.
