No. Karl Marx -- regardless of the massive misinformation and ignorance about his actual writings, his actual stances, and who was/was not actually inspired by the same -- actually got a lot of things right. He made major substantive critiques of capitalism, both as manifest in his own times as well as predicting major problems within capitalism which came true long after his death. Regardless of how one may feel about his recommendations, his empirical findings and analysis are well grounded in observations almost anyone can reproduce.
Ayn Rand, on the other hand, doesn't have a leg to stand on (intellectually or empirically speaking), used a patchwork mess of private definitions (different from and in some cases practically the opposite of their typical usage), thin and transparent characters, and hysterical overreaction to living under false communism as a basis for rationalizing her pathological "philosophy" (which, ironically, ended up operating like a religion, with a mindless individuality-crushing inner cult of its own).
