Uberti uses a modified coil spring action, and I think the C.Sharps has the original flat spring style.
I know next to nothing about the spaghetti rifles other than they run the gamut from low-cost, low-end to very nice (Pedersoli), but difficult to get repaired or finds parts for.
There are two High Wall makers in the USA at the moment. C. Sharps Arms is a coil-spring action (post-1906 design) that is faithful reproduction of the original. C. Sharps will build you a High Wall in most any rimmed cartridge and configuration from around $2500 to as much as you want to spend.
The other High Wall builder, MVA (Montana Vintage Arms) offers only a complete action, which is a flat-spring (pre-1906) reproduction. Like the C. Sharps, is an excellent piece with great support. But, you need a gunsmith to add wood and a barrel and finish work.
1874 Sharps from the USA are offered by C. Shaprs and Shiloh Sharps. Both are excellent quality and, again, start at around $2500 and go to as much as you want to spend, with all sorts of trigger and wood and finish options.
There are major differences between the two rifle designs. The High Wall, when fully opened, cocks the hammer when the action is closed and it is ready to fire. Once fired, all that is needed to eject the shell is open the action fully. Fast & simple with no manual cocking of the hammer required. Also, the High Wall action has a good amount of camming action so a longer cartridge can usually be fully seated by just closing the block. The High Wall is the simplest of our actions with exposed hammer for actual use.
The 1874 requires one to place the hammer at half-cock prior to opening the action to prevent dragging the firing pin on the case and eventually breaking same. Once a cartridge is placed into the chamber it must be fully seated as the Sharps action has no camming action to speak of. Once the action is closed the hammer must be fully cocked manually.
In actual use, the only spare part that one needs to carry with the High Wall is a spare firing pin. With the 1874, a spare firing pin, transfer bar and a couple of the springs are suggested.
Both can be highly accurate when in the hands of someone who knows how to load for and shoot the rifle. Pick the one from C. Sharps, MVA or Shiloh Sharps that appeals to you the most and enjoy.
