Reef Breeders or Tunze ATO?

[Waffen06]

So I have a Tunze 3152 nano ato from an old set up, did what it needed to. Just bought a complete setup and it came with a Reef Breeders EXO with the optic sensor. Which is better in everyones opinion? Ive had little snails get in the tunze sensor or it just seize and Im sure on the RB the sensor needs cleaned to prevent buildup. Which should I keep?

I’ve had the normal tunze osmolater 3155 since my first tank in 2006. It has never failed me and is rock solid. If/when it finally dies, I’ll replace it with the same unit.

Reef breeders has more safety features and uses an optical eye witch is better then just a float switch that tunze nano uses. I've had them both and I like the reef breeders better.
