I figure I may as well jump in on this thread.
The way I see it, bows can be judged by their performance, by their fit/finish, and by their intangible value.
What I mean, is that some bows shoot well, some look amazing, some are special for reasons which have nothing to do with the bow itself (heirlooms/special back story/etc.)
Truly exceptional bows meet all three criterion.
Some folks only care about performance. (To my mind they miss out on a very large, beautiful chunk of life, but that is just my opinion.)
Not many people want a bow that looks pretty without performing, but the intangibles might make up for it(example: _____made this bow for me a year before________ so I will never get rid of it, even though my ______shoots better.)
If you care about performance, but appreciate art, a custom bow is the way to go. Humans in general are drawn to beauty AND performance. A good bowyer will work with you to make a bow that you might never want to sell.
I am lucky. I have a beautiful bow that performs at a very high level, and it survived a vicious car accident with me (my intangible). I consider myself fortunate to be in the position I am. There is no need for me to look for something better. I might find another bow that is as pretty, and shoots as well, but it will never have the same special feeling as the one in my possession right now.
