CVL are much cheaper to sortie. They tend to have less plane slots but often times you don't need a full carrier or need CVL for branching. Plane damage and air superiority is related to plane slots by a function of sqrt, so you can often still achieve great results if you have good quality planes, at a much cheaper price.
