How does Black Wow, Black Again and Forever Black compare?

Are these products worth the purchase? Would you prefer to use one of these products or some other more temporary trim application?

I've used Black Again and Forever Black and was not impressed...Once I seen the Black Wow video I was sold. I ordered a bottle and it should be in soon for some testing - I will post pictures on the BMW I apply it to this weekend
