Jandy SWG - iAquaLink Need Help Choosing SWG

I read a lot of issues with the Aquapure. It looks like the Hayward has many issues as well. What seems to be the most reliable? I'm between the Aqualink, Hayward, and Circupool right now.
Circupool is best value and reliability if you don't need the automation control.
 
Jandy’s AquaPure (Model PLC1400) connected to your Aqualink. It is a more robust system then the TruClear.


I have it and so far it's been great. I have it on 17.6k gallon pool so I have plenty of cushion yours is much closer 40k capacity on 35k pool. I wonder if you can use two of them to have a major cushion vs running that one at almost a 100% for that size of pool?
