In a way, the dynamic between Brannon Braga and Ron Moore reminds me of the dynamic between John Lennon and Paul McCartney. Moore's stories always seemed grittier... punching at your gut, while Braga's were more esoteric and more low key.
Together, just as with John and Paul, their strengths blended into a superb writing combination. Separately, I prefer the gut punching of Moore and Lennon. Maybe that's why I listen less to McCartney solo stuff vice Lennon's and don't really watch Voyager... a show I often found rather mundane.
