How far down the rabbit hole are you willing to venture?
If you completely believe that muzzleloaders WILL NOT become a primary hunting firearm, and that you'll only shoot it a few times each year just prior to hunting, then here's my suggestion................. Remington Ultimate. Its also a .50cal, so if you were to hunt in states like CO, you can shoot bore size .50cal bullets. Its pretty much a "no brainer" muzzleloader. It is accurate to 300yds+ also. Cost effective also, which allows you to spend a lot more on a quality scope. There are a couple modifications that make the RUM a very good shooter.
And............ if ever down the road you want to get really deep in the rabbit hole, the Remington 700 action on the RUM can be used to create an unbelievable SML/SMOKER muzzleloader.
Myself, I'm not putting $5k - $7k in a BOTW muzzleloader. You can purchase a TOP OF THE LINE custom build and IMO a better rifle.
The Paramount.............. Although a success for CVA, it leaves a lot on the table. CVA has the inside barrel diameter as some kind of SOB. Their reason behind that........... sell CVA Power Belt Bullets, specifically the ELR's. The bores are oversize and if a person wants to use a different bullet, generally a .452" bullet will have to be knurled and resized to shoot well. Don't get me wrong, there's been a lot of game that has fallen to the Paramount in a short time. I'm not a fan of the vari-flame ignition system. Its also a 45cal unless you went with the Paramount Pro in 50cal., so some states you'd be limited (CO).
All three of the muzzleloaders you mentioned are 300yd+ muzzleloaders.
