Noise reduction is generally effective in dark areas because there is little detail to retain. Most noise will be chroma (color) noise so it is easy to remove in your RAW processor or with third party noise reduction. Remember that there is no "correct" sunset exposure. I always bracket widely and choose the best result.
An alternative to "exposing to the right" proposed by @mattdm could be noise reduction through image stacking: align images (all images taken with "as identical as possible" intrinsic and extrinsic parameters (view point, focal length, etc.)) stack aligned images as layers in a single image blend layers using median/average/...
This is a perfect example of "expose to the right" — that is, even though you want the final result to be low key (largely dark), take the initial exposure as bright as you can (without blowing out the brighter part of the sky, reflections, or any more subtle brighter areas). When you expose so that dark areas are really dark — either because you are ...
The short answer is both, but it requires some explanation. Megapixels. Yes, but only if we're talking about 12MP vs 24MP for a given sensor size. The issue is not the absolute number of megapixels per se, but the size of each individual pixel. Buckets in the rain is the common analogy used. Essentially, if you have two buckets out in the rain, the bigger ...
