Those happen to be my three favorite Doughboy pools. The Copper Caynon and Riviera designs have been around for over thirty years. They change the colors and the names to keep up with the times. They are both good, solid easy to build pools. As far as Resin top rails and uprights go the Desert Spring is by far my favorite. I feel most pool manufactures have way overdesigned the above ground pool. To much plastic and way to many parts. Way to many parts that just do not fit as intended and can make installation a real pain. Doughboy built a nice looking resin pool while keeping to a very simple, user friendly design.

I would put the Sand Dollar in this list and say you could not go wrong with any of them. Top quality, user friendly.
