Unless you're looking for an exact period specific model, considering all elements of quality, style, appearance, accuracy, low price, and unbeatable lifetime warranty, in my opinion nothing else compares to a TC Hawken, both percussion and flintlock.
PS: TC's recent flintlock production includes major design improvements starting a couple years ago and they are now absolutely flawless...I have several in various calibers and they're outstanding.
Took Deer with .45, .50, and .54cal TC Hawken Flintlocks last year, and usually shoot one of them every weekend at the range...get some good quality Tom Fuller Black English Flints from October Country and shoot all day.
