Dometic or Norcold? Electric?

I've had all three, Dometic, Norcold and now an Atwood, to me they all perform really well. My current Atwood has a fan that cycles on and off all the time and I've found that it cooled at a lower setting better than my Norcold one. I've actually had to turn it down because things were beginning to freeze. It also has a larger evaporator tray and doesn't end up dripping water in the fridge like my previous two fridges did.

The feature that I like is that the helium is not flammable like the hydrogen was on the other units. Having said this though, I would have been happy with whichever fridge came with the trailer when I bought it.
