New Pool AOP system

I am wondering what your thoughts are on the AOP systems, the Solaxx Renaissance system to be exact. Originally, I wanted a salt water system, however, our pool builder is swaying us away from salt because of worries of corrosion to the automatic cover, and he is pushing for the frog system which I am having mixed feelings about. Our builder said one other option is the Solaxx system but he would still pair it with the frog system. What would you recommend for a new pool sanitization system for a 20x44' pool. Thank you!
