Ours started out as a salt water one 8 yrs ago. It is now chlorine. Got tired of replacing the cell (2x and now waiting for 3rd) and last straw was the controller failure, and that was 2 summers ago. May convert back if they ever get more reliable systems. When it worked - it worked good.
They boast maintenance free with these systems but nothing ever is with pools. However, I am in Canada and components here are much more money and availability and service much more limited.
If you are okay dollar wise with planned replacement of certain components like cells ever few years - then go for it. You may want to discuss with your local pool supplier and see how long these systems are lasting in your environment.
My wife is the pool master now, even though I am a chemical engineer she has this pool chemical science down. I just swim and drink rum
