One comment on the article; he may in fact have compared the black ones to "crappy - poorly made Maxell, TDK type discs", but he used arguably the crappiest brand of black disc available, namely Memorex. Most folks around here wouldn't use Memorex if they could choose a 10 cent store brand instead.
That said, I don't have an opinion on black discs. I will admit I'm curious to compare, if I could get some black ones made by a better mfgr. My suspicion is that psychology is more relevant than engineering on this one. But I'm trying to keep an open mind till I get to make a thorough comparison myself.
I will confess that I think the black discs look cooler than anything except maybe the gold ones.
