I agree with you Roger and disagree with Crash's assertion. To me as well, there is no functional difference between any of the top end cablesets including Jagwire's Racer set. Testiment to this? All that have weighed in love their cablesets...universal praise. In contrast with this are all the complaints about shift quality which almost always leads to set up versus types of cables used.
