270sniper,
If I were you, I would go with what shoulders/feels thebest in your hands. T/C and Knight both make top notch muzzleloaders.
I shoot bothT/C and Knight's and I'd say that they are pretty well equal in the accuracy dept. once you find a load that works well in that particular rifle.
I don't like having to buy disc's and wish Knight would offer a ML that didn't require using them.
They are pretty well equal in quality / reliability / warranty / customer service etc.
