The very best of them all, IMHO, is the Hagn, its construction is superior to everything else. Next is maybe the Dakota, more or less a copy of Hagn's design, at least he said so when I visited him in 1990. But I doubt that, to me it looks like a totally different action.
Since I cannot afford either of the rifles mentioned, I am looking for a Browning 1885 High Wall as a basis for a custom hunting rifle, this action is also of remarkable quality and I like the exposed hammer.
As I said, just my humble opinion.

Wicked good hunting !
