Chris, as I said, still learning about these, but....
That flinter looks like a very nice Lehigh-type longrifle, based on the shape of the stock, and length of the barrel.
The percussion rifle looks like a very nice sporting arm, and looks like both would be a delight to shoot. I seem to like the drop of the buttstock in this style of rifle.
Some of the people here on the forum see exactly which "school" of firearms, quicker than the eye can blink. I just go by what looks "nice" to me, and these both fall into that category.
Do you plan to enjoy shooting these? Now, to me, that would be fun, checking them all over to see how healthy they are, then trying to acquire the correct ball, patch, and load for various conditions.
They are, indeed, beautiful works of art.
