High frequency launches is only one element.
Sustained operations is also very important as nuclear power allows carriers to have more range and aviation fuel, but it still means the Nimitz can only conduct 16 days of continuous flight operations.
From a cost versus performance perspective, remember that US Navy studies keep emphasising bigger carriers (as hull volume to store fuel/weapons is cheap) and nuclear power for greater range / hull volume.
Plus reactors mean a lot of electrical power available for defensive lasers in the future.
