There is no "Best"

This is a "Best" from an objective quantitative point of view. A "best" seller" when new, a "Best" seller in the used market, a "Best" color seller, etc. etc.
I think when most ask what is the "best" what they're really asking is what is considered good. I know at least in my case I know nothing about PRS guitars but wanted to try one out without making the mistake of basing my opinion off a POS model. So I may ask which is best just looking for options that won't be poor examples to base my experience on.

For example if I were asked what is the best Gibson Les Paul I know there is no such thing but I would probably answer the Custom Shop, Premium or Custom.
