That is the problem with such a question…
So, for one to have the perfect “One for all” rifle, it MUST be .375 or larger so as to be legal for dangerous game.
In that light, I would take the 404 over the 375 simply because it can be loaded well over the 375 at the upper end and still loaded way down with cast bullets to be useful as a deer rifle.
I guess I can endorse the notion that the 404 could fit the bill…
