IMO there's nothing wrong with a "fancy" muzzleloader, or one that looks ugly as sin. There's also nothing wrong with a muzzleloader that costs its owner $300, or rather it costs him $3,000. However if every muzzleloader cost $3,000, there wouldn't be as many owner/shooters either. Custom built muzzleloaders cost money to design, engineer and manufacture.
Some owners like a safe full of low to medium price rifles, others are happy to have just one higher priced and quality custom built rifle. Nothing wrong with either...... This new Cooper just won't be a rifle for everyone and that's ok too.
If anything about a new custom rifle hitting the market surprises me, is that its only a maximum 150gr capable rifle. IMO it would have increased interest in more prospective buyers, had it been capable of heavier charges.
