Have been browsing individual threads on each of these products and just thought I'd start my own thread with a more specific format to gather info that highlights the pros and cons of each. I have emptied my pool and want to install one in the pool and spa, but am stuck between the two. I have read all the stories on the Haywards crapping out after a year, so I'd love to hear an update from anyone who has a recent, more revised model like the 4.0 to see if those kinks are worked out (lip/tab/seal issues, etc.) I like the Sangria controller for the CL4.0 better, but I won't install it if the core functionality is still in question. I would also be interested in knowing if either product can be found cheaper. I have found the Pentair for ~$500 online but haven't had much luck with the Hayward outside of "authorized retailers." My local pool shop wanted $2600 to come and install a pool LED and spa LED along with the transformer wiring. This was without the controller, IIRC. This seemed a little high, and I am considering doing it myself, but don't know if it's such a good idea since I'm not a licensed electrician.
