Most reliable ATO?

Tunze. Spend the money. Well worth it.

Bit the bullet and went with Tunze Osmolator, never looked back. One of top 3 investments I've made in the tank. When you add Tunze's legendary customer service, it's a no brainer.

I have the Apex controller so I purchased the autotopoff sump bracket and two float valves. If I didn't have the controller I'd get the Tunze Osmolator for sure.
