I was a big Preben Holm fan in the early 70's, mainly based on style; those freehands turned the staid world of classic shapes on its ear and started a movement. A little heavy and poorly balanced, but easy on the eyes. As smokers, however, I thought they were, mieh, just OK.
I've found GBD's to be comfortable, very affordable, and consistently good smokers, but are difficult to find outside of e-Bay these days.
The only 2 Nørding's I have are excellent smokers.
I recently bought my 1st Savinelli, and I'm very impressed -- an affordable, everyman sort of pipe that smokes as well as any GBD I've ever owned. I'd put Stanwell in the same class, and for the same reasons; but like the Savinelli, I've only got one example from which to draw conclusions.
Looking forward to one day owning an Ardor, Castello, Luciano, and Cavicchi -- but that's based solely on looks.
