Strictly talking about the steel burr set though.
Fair enough based on that parameter, though I'm not sure there's significant consensus on uniformity and particle distribution being correlated strongly/reliably enough to in-cup espresso results, though I guess that's the best objective measure we have. I think, if I recall correctly, some fairly well regarded grinders not scoring so well in that area and some low-end grinders likewise doing well. That said, personally, I'd still consider the build quality, true stepless adjustment, and reliablility of the above hand grinders as clear and substantial wins over the Vario. Whether or not those qualities matter versus uniformity and convenience is another question.
I guess what I'm saying is that I think we should be skeptical about reductionist claims until they are verified. I think that if we pare down 'quality' to one quantitative variable without first verifying this variable as the sole or major contingecy of essential quality, then we run the risk of not truly measuring or achieving quality.
