Since they are in the same pitching field I think you can make your choice on arrival. I believe the C&CC site is in the lower part and the CC is on the higher level, with views of the sea.
On balance I think the CC pitches are better positioned but there is now a newer toilet block in the C&C club area which is excellent. In practice, people tend to use either block. The only advantage of some of the C&C pitches is that they are more sheltered which can be a blessing when its very windy - if you're at the top of the site you'll have trouble keeping an awning up if the winds are as strong as they have sometimes been when we've visited.
Good shop on site and although the owners run a tight ship they are always helpful and offer to make you a tea or coffee when you arrive.
