At a practical level, the Vulcanite versus acrylic question means almost nothing to me. However, given the choice, I prefer a quality Vulcanite to an acrylic stem, for a little extra comfort. But I can't deny the ease of maintenance and the snappy sustained appearance of acrylic stems. Even a little oxidation that is easily cleaned is just slightly demoralizing.
Also, I like some of the colors that come up better in acrylic than in Vulcanite, though some Vulcanite Cumberland stems are quite handsome.
As relates to the White Spot brand, at almost any price level in the White Spot line, you can get a better pipe in a different brand, or two pipes in many cases. It only requires you know a little more about pipes.
