All of the 470 class are so close to equal as to be not worth mentioning. The 470 has the advantage of Federal loading for it. That is if your rifle shoots the Federal. Double Rifle ownership requires reloading, it is the only way to do it.

I like the 450 3 1/4 because of the slimness of the action compared to the others.

A 458 Lott would not be a good idea as Doubles do not do well with rimless cases. No one has ever come up with a fool proof ejector system for one and the pressure is usually quite a bit higher.
