It's a stone engineered to be a diamond replacement, as the article mentions. From there, what would you like to know? (My wife's a jeweler, so I'll probably have to forward the harder question, but as study-buddy for her gemologist education I know at least some trivia :) It's... a different stone. You can usually tell cut diamonds and moissanites apart with the naked eye once they reach a sufficient size. (Moissanites have a telltale rainbow sparkle, diamonds don't. Large moissanites have a color tinge, "good" diamonds don't) You can debate which one looks better - I prefer diamonds with an old european cut, because they're spectacular :) - but ultimately, it's a rock. You buy a pretty bauble because you like how it looks. There's very little intrinsic value here.
