No offense intended to anyone, but the "best" handling issue is one that has had my attention for some time. I have come to the conclusion that there is no particular "best" handling. There is is a wide range of handling dynamics within guns that are usually considered "best." So, it is not at all unusual to find one that meets your view/preverence for handling and another that doesn't. The "doesn't" is no less a "best gun," it just had handling dynamics that suit someone else and/or suit a different purpose.
Consider a Purdey game guns and Purdey pigeon gun. Not likely that anyone will argue that either is not a "best." Likewise, nobody is going to argue that they handle the same. If you study the subject, you will find that preceived handling depends on a number of factors that are not part of the dynamics involving muscle effort. That is to say, most people are influenced by such factors ar their view of the brand name, the aesthetics, etc. Handling preference is like stock dimensions preference --- individual!
