I've done both, but not in the same style, so I don't think a comparison is accurate. However, I will say this: On a price per "performance" basis, I think that cellar craft wins hands down.
What we really need someone to do (and I might), is take 1 year, and make all 3 supertuscan products. Cellar Craft Rosso Fortissimo, RJS Cellar Classic Winery Supertuscan, and the W/E SuperTuscan Crushendo. Then you will have 3 examples of the same style. Wait 1 year after fermentation, and do a blind taste test.
