The Røde® NTG3 seems to have a narrower polar pattern than the Sennheiser® but the NTG3 is much pricier than the Senn 66. The NTG3 is also not as sensitive as the higher end Audio Technica® in the same comparable price range. More latitude, however, can be a good thing when you're dealing with soft and loud vocals during the same (interview) take. My AT4073a is a nicer sounding shotgun than my NTG3, which sounds almost muffled by comparison. I can't speak to the sensitivity of the Senn 66 but I know it's considered a 'hot' mic.
