Mykonos, famous for only its limitless nightlife, can offer a lot more such as a visit to Delos -the core of Cyclades- or a day full of pampering at one of the world-famous beach clubs. On the other hand, Santorini can offer swimming in its dark colored volcanic beaches and a priceless sunset during a catamaran ride.
