Oh boy, obviously you and others do not know what a custom rifle entails. Accuracy/cosmetics are the only items on your list, to compare to a manufactured rifle? I believe that you and others have a rigorous, in-depth research into a custom rifle, to expand your knowledge.
Custom rifles are made to a particular individuals likes/specs.
I believe the OP wanted a comparison of accuracy/function/value retention.
I've seen some lovely custom rifles offered up for sale at half the original price, sit on the same vendor's tables for several years.
Always something that turns most people off, length of pull, cartridge chambering, stock type etc.
Your and my idea of what makes a perfect rifle is a personal opinion only.
