Since I own all three of the pistols you are considering, I will throw my two pence into the mill pond...
1858 Remmy:
Very nice, strong frame revolver. I have ZERO problems with the cylinder pin sticking when using Pyrodex P, which is non-progressive fouling, even after an afternoon of shooting. (That last specially for you, Pete!) Nipples are a bit of a tussle to cap with a straight line capper unless modded (as discussed in an earlier thread.
Sights are easier to use being a groove in the backstrap, as opposed to a notch in the hammer. The grip is slim and thin, nice for smaller hands, and allows for all three fingers to curl around it. Loading lever stows nicely and functions well. If I had to count on one in battle, this would be the one I'd grab.
1860 Army:
This is a full sized gun with a large grip. The creeping loading lever is a bit of a mystery still; feeling awkward. You need a hunk of wood or similar to pop the barrel wedge loose, and once you re-seat it, you have to be careful tapping the wedge back in as it can close up the gap between the cylinder and forcing cone easily and lock up the cylinder. Mine has the sweetest, lightest action of an BP pistol I've ever handled...might be due to the many hours spent snoothing and shaping the sear and hammer when building. I like the brass blade front sight the least of all my guns. Still, this is a man's gun when loaded with a .44 conical and 35 grains of "P".
1851 Navy:
I hated this gun when I bought it. Action was terrible; fit & finish sloppy. The only thing I liked was the looks. After a total makeover, this little .36 is one of my faves ever!
Capper is dead-nuts on this one; this gun points better than any other BP pistol I've ever handled. Look at a distant object. Close your eyes. Now, raise the gun and point where you THINK it should be....Open your eyes, and...BINGO! The grip is fat but short. You can squeeze it with two fingers and curl your pinky under the grip. For some reason, I find this comforting and easy to control?
The loading lever is sorta loose and sloppy, but not unpredictable like the '60. Even with a conical and full charge of powder it's mild on recoil...pleasant to shoot. The front sight is merely a pointed brass rod..simple, effective, and graceful. The gun has an "Old School" look with it's slab sides, octagon barrel, and brass grip frame. Pick one up and handle it and you can understand why Wild Bill made them his choice. Yee Hah!
In the end, the choice is yours. I STRONGLY suggest you handle one of each before making an impulse buy. They DO all feel different. Good, but different.
