I agree with Bryan and Mike, but since you've played both courses before, it's really up to you, and what you want out of the experience. If it's relaxation/chilling out Chechessee wins, but if it's challenge/hard-ass golf you must play Harbour Town. If it's architecture you are looking for, both are instructive, but from different perspectives. HT is designed as a tournament course that will beat you down if you do not concentrate on every hole and every shot. CCC is the classic members course, which will leave you walking off the 18th with a smile, no matter how well or badly you play.
