I am torn. For me the Remington has more "practical use"
Besides being very valuable for SD/HD , you can also hunt with it. The shotgun is like the swiss army knife of weapons. Doesn't have the range of a rifle, or the size of a handgun but has lots of power close in.
The colt may hold its value, may become more valuable true true and you can CC it but as far as pure utility IMO it scores lower. It all really depends on what you are looking to do with the gun, if this is a collection piece or for something else.
If you were putting me out in the wild with one of these firearms though it would be the shotgun hands down.
