I started with a Pietta Remington New Army. It is simpler to take apart, not having the wedge. The solid steel frame (with topstrap) is a plus, as well as the fact that the rear sight does not move when the hammer falls.
I once borrowed a Traditions 1851 "Colt" from a friend, and had a heck of a time removing the wedge. I ended up shearing the wedge spring pin and had to replace the wedge assembly as a result. Also, I had to narrow the first wedge (front-to-back dimension) to allow the cylinder to turn freely. I never shot the gun with the replacement wedge, but wanted to return it in proper condition. I gave him the old wedge too, since it shot fine without a wedge spring.
I am currently shopping for a repro of a Colt to get the "Colt experience," but honestly believe that if I had started with a Colt, I might not have stuck with cap and ball.
Remingtons are much simpler to operate and certainly stronger, in my opinion.
