Realistically it’s the law of diminishing returns, to a point money buys large leaps in quality and performance however you reach a point where the relationship switches and small gains cost more and more. I’m more familiar with guns for an example but it kinda goes like this
$300 to $650 nets you a budget rifle that shoots reasonably well with a rough action and a cheap hollow stock. Example - Rem 783, Savage Axis, Ruger American, Mossberg Patriot.
$1000 to $1500 nets you the flag ship production models, smoother actions, nicer stocks and more little features. Example Browning X-Bolt, Rem 700, Winchester Model 70, Ruger 77
$1500 to 3000 nets you a combination of premium flagship rifles and budget custom builds, for production guns this range is typically reserved for the best stocked rifles in the line up with either fancy wood or special fiberglass. For the customs this is reserved for custom actions with premium barrels and more budget friendly stocks. Typically this is where the performance envelope stops improving and simply becomes more tailored to a specific application.
$3000 to $6000 nets you a custom precision rifle, pick your poison but a top of the line custom action with a premium barrel and stock sent to a well known smith will fall somewhere in this range. They are all incredibly accurate and the cost variance is entirely based on what features the customer requires of the rifle.
$6000+ with the exception of AI and Gunwerks this is full blown custom hunting rifle territory, exhibition grade wood, engravings and titanium parts rule this range. With the exception of AI and Gunwerks this is all luxury based, they don’t shoot any better but they sure do look pretty doing it.
I imagine crossbows follow a similar pattern with the Ten Point and Ravin representing the top tier. They are slightly lighter, slightly shorter, slightly thinner, slightly faster for double or triple the price of similar models offering 90% of the features and performance. To some people that extra 10% is worth the extra cost.
