Comfort fit means the inside of the band is domed rather than flat, so it rides on a narrow ridge instead of gripping the whole finger. It goes over the knuckle more easily and traps less moisture underneath.
Serene is a plain band done properly: 4 mm across, 1.8 mm thick, high polished on every surface including the interior dome. The extra metal is the point — a heavier band holds its round instead of going oval after a few years of wear.
