Is Alienware Worth It?

Now I find it hard to believe that Alienware (which is apparently the best PC brand in the universe either one of those, but somehow people seem to be arguing that they're both. Basically I need some real info on weather or not Alienware is the real deal. Is Alienware really this insane PC brand that provides the best of the best hardware in every new Laptop/Desktop that's released.
