More of an issue for me is smaller pixels have smaller well depth which can lead to weak stars that are easily damaged in processing and you have to be more careful to retain colour, shape and look.

so the 4X sensitivity drop was just around the reduction in flux on the pixel due to the area which would be 25 microns squared as opposed to 100 for the 10 micron pixels
the point about well depth is a good one because stars are point sources then the majority of light will be concentrated on a few pixels regardless of the size and that is likely to become saturated, but larger wells will have this issue in longer exposures ...
