The most important aspect of wanting to compete for the Pop-A-Shot National Championship is to practice. It doesn't matter if it's on a Pop-Up Game or a Pro Series Game. Sure, there will be some differences between the home games and the Pop-A-Shot Elite Arcade Game but if you become comfortable with the shooting mechanics, finding a rhythm, and overall comfort handling the size 3 basketballs, you will do just fine.
If you're training to compete in a Pop-A-Shot qualifier or want to replicate that Elite Arcade Game experience at home, the Pro Series (Pro Dual Shot or Pro Single Shot) is your best match. They come closest in dimensions, rim construction, and gameplay speed.
For casual use, family fun, or smaller spaces, the Home Series (Home Dual Shot or Home Single Shot) still delivers a great experience, just with more flexibility and a gentler learning curve. The Indoor Outdoor Dual Shot adds weather resistance, the Dual Shot Sport maximizes portability, and the Pop Up Game is unbeatable for quick setups.
