Hate or love her, Rand had a powerful way with words. You can admit that and still thinks she was the evildoer. By her influence she was one of the greatest expository writers of her generation. She brilliantly wrapped treatises on economics and philosophy in sugar pills of fiction. For good or ill, Howard Roark is among the great literary characters of the twentieth century.
What I guess you can say is that being a hypocrite and narcissist herself, Rand knew her audience quite well and wrote accordingly. There's a lot that can be learned from that.
