8 Pellet has as many/more fliers in my experience. It's buckshot. DO NOT TRUST IT if you need precision. Its performance is very variable. I've had #1 buck from the same gun, 2 shots in a row, 1 looked like a slug at 25 yards, and 1 had pellets outside of the 8" circle. You just cannot trust it. It's for targets where there is no serious consequence of a pellet coming off, or for when you literally do NOT have another option (not issued slugs, do what you gotta do, etc.)
Just my .02
