How many hours you got ??
Both are good rides but with both plan on changing the controller if you plan on the larger tires. Neither like it for long. Just the nature of the motors in those. I'm more of an EZ-Go guy so not sure about aftermarket part availabilty for the CC but there are thousands of them out there for the EZ. Also, I believe parts tend to be a bit higher for the CC, at least in the lift category.
my 2 cents
