Along these same lines there really isn't a best, atleast a single only one option for most situations. What one person uses may not be suited for what another does, especially when it comes to shotgun shells. Each gun patterns differently with various loads and it behoves the shooter to spend some time at a clays range or atleast at the pattern board to see what really does best for them.
An example, someone asks whats the best waterfowl or even duck load. If you are teal hunting small shot and the xpert loads do fine, atleast for me yet someone that is hunting seaducks on the coast would prefer something with more punch, and someone timber hunting in AR would make a different choice, same as the guys gunning over blue bill dekes. Different situations call for different tools.
