Nobody could know. Even among selective niche’s, there are too many masters in the craft for any one of us to have touched enough samples from each to have any hope of an educated opinion. Best 1911 builder, best 2011 builder, Unlimited bench Gun builder, open Precision Rifle, 10/22 racer builder, M92/9 builder, levergun smith, scattergun smith, 3 Gun gas rifle tuner, etc etc. Entire classes among them, and folks simply don’t live long enough to have tried them all long enough and side by side to make the exceptionally close determinations between great and slightly greater.
And naturally, a master of all is a master of none, and a master of one isn’t a master of all. So when we see a master bench rifle builder, he’s probably not the best resource for a custom 2011, and the most broadly skilled repair and restoration master likely has no sense of any competition specifics which are critical in that field.
