I would venture that it would to a large degree depend on the hand making process involved, and the current generation of craftsmen, plus CNC technology available today that was not used in the past. Are the craftsmen of today inferior to yesterday's generation? Has the technology advanced from generations past? With regards to Getzen, just to pick a name I am most familiar with, both Mary and Bret went to great lengths to give me an education on the craftsmenship required for a new trumpet that wears the Getzen logo. I agree there are some vintage horns that are awesome. But equally, there are current models from different manufacturers that are as good, although they will lack the nostalgia factor.
