I think it depends on individual taste.
Peter McDougall's work is definitely of very high quality, but I sometimes feel that his weights are technically "too perfect" for my own preferences. However, I do tend to focus on the more rustic look of earlier Ysart work!
And I do think there are some antique French weights that are of an equal visual quality to those of some of the modern makers. And some Americans, such as Jim
Hart [Edit ... please see correction below], also produce superb millefiori weights (and Jim has only been working in glass for a relatively short time).
Mike Hunter's work is another case of techinical excellence in cane structures and setting.
