For me, it depends on what skill level you are at. Genesis teaches very basic and beginner material, while the Trilogy is more an advanced DVD. Teaching wise, I believe Genesis teaches better than the Trilogy. Genesis teaches over the shoulder with Andrei narrating. While in the Trilogy, D&D teaches from a face-to-face point of view and they do not speak at all, there's only subtitles. Good luck on your decision anyway. Hope that helped!
