That is debatable but from my experience the number one system right now is the Pentaier Intellichlor IC40
The next major brand and in second place would be the Hayward Aqua Rite system.

Then you have the smaller companies who are the ones that originally started the salt pool movement.

So if you are thinking of going with a salt pool there are a lot of systems out there to chose from. I will make it easy by ranking them for you: Best:
1. Pentair Intellichlor (excellent)
2. Hayward Aqau Rite (very good)
3. AmericanSPS Nexa Pure (very good)
4. Zodiac LM-3 (tested and is good)
1. Jandy Aqua Pure
