What do you like. My son has one that is rarely used because of the cleanup required after shooting. For us it is simply too much trouble for a one shot rifle. I am open to suggestions, but we have come to prefer crossbows.
I have hunted with both pistol and rifle, both in cap and ball and flintlock. Even went so far as to build some of the weapons myself from kits. Crossbows too.
For me it is like riding a motorcycle... It is the trip the counts, not the destination.
Besides, I am not too keen on being out in the woods when every great white hunter from the burbs is there with their semi-auto doing the spray-n-pray at every little noise or movement.
BTW...
My favorite is probably the CVA Optima with a Red Dot scope

It takes a month to wipe the smile from my face every time a pull the trigger.
TC Encore and Blackhorn 209. As easy to clean up as smokeless powder. 1” groups at 100 yards. For hunting in a state that only allows shotgun muzzleloader or handgun for deer the muzzleloaer is the way to go.
We have several cap & ball and one flint lock. Most are kits. Three revolvers, one a Colt Walker. Smallest bore .32, largest .58 that uses a 620 grain civil war bullet.
We are into traditional muzzle loading only. None of this modern inline stuff.
The modern belief is a black powder weapon needs cleaning after each use. Think of it a minute, did Crockett or Boone meticulously clean their rifles after a days use? Did they have the bore brushes and the solvents of today?
I’ve let rifles hanging on the rack for up to a year with no cleaning to prove this point. But I do run an oil patch down the bore first, and I sorta suspect the frontier folks ran an animal grease patch down the bore in lieu of a thorough cleaning.
