I see no advantage to one over the other except in small details. The Siller will have a nitrided bolt. As long as you can get them with a pinned recoil lug, this is a fine way to go and not giving up much to the 591 or BAT one piece.
They are both outstanding actions. If you are going with a #3 contour barrel, it makes no sense to use the heavy BAT or 591 action.
I recently tried to buy a Rimrock but the wait was too long. We went with a Pierce. If I had to do it over again, I would do the same thing.
I have a Defiance long action and it is bank-vault solid but the one piece bolt adds $500+ to the price of an action.
