Use what you feel comfortable with. If you and your gun shoot 8 balls better than 12, then just shoot again and your already ahead 4 balls.
000 buck is not necessarily better than 00 buck. The larger the pellet the further it penetrates. The smaller the pellet the more tissue is impacted by the payload, and more lead can be fit in the shell.
The ideal size pellet is the smallest one that can penetrate deep enough for a given target.
Even 00 buck is considered larger than needed for humans, and as a result has less stopping power than a couple of the smaller buckshot loads at close range. The reason it was chosen by police over the years is that it is more versatile.
Larger pellets retain energy better at range. They can also penetrate some light cover and still provide some stopping power or wounding that a pellet optimized for direct impact would not.
I keep Federal R/R 9-pellet 00B in my Benelli mainly because of the super-tight patterns-- +/- 4.5'' at 15 yards. Quick follow-up shots are very important, so that's--as previously mentioned--a big reason to go with these R/R loads.
