I assume we are talking engineering aspects and if so the Beretta 626 action slams the Anson-Deeley. Its bits work under compression not tension and steel's strength is better used under compression. It has cylindrical recesses for the action parts, coil springs, incorporated double safety notches in the tumblers, replaceable cross pin and it is hardened throughout. And if anything breaks it can be replaced with no hand fitting required. The action bar is chamfered to accept the filleted monobloc barrels.

Being Italian it has no "best gun"cache, but objectively it is the better system. External appearance wise it is identical with its three axles to the AD for those that like such details.
