It is best to know how separate parts of the photographic system works.
Lens contrast: it's the quality of the glass, it's transparency. Less transparent lenses produce low contrast and washed colors.
Lens precision: it's the ability to reproduce the image clearly. Very precise lenses reproduce sharp images, even at the border.
High pixel count in camera produces more noise since less photons fall on a smaller surface (the discrete pixel's surface). But the noise appears at pixel level, this means more fine noise, in this case stronger noise filtering can be applied while the actual image details are less affected.
Basically the best camera system is one with the highest megapixel count as possible and the best mechanically executed lens with the most transparent glass.
Disadvantages are high storage capacity needs and stronger computers to process the images.
