Not arguing with anybody.
I picked #4 buck in 12 gauge and #3 buck in 20 gauge years ago for home defense shottie loads. In my home , in my neigborhood , with a armed citizen's job description -- they seemed like good loads for inside the house or condo. I never have and never will own a home big enough that any normal pattern spread will be a significant disadvantage.
IMO, LEO/military ammo choice criteria are sometimes different than armed citizen considerations. The main go-to guns at our house are Glocks and AR middies now , but the shotguns are cruiser ready in the same locker. We keep them mainly for house guests or neighbors in need.
FWIW & YMMV.
