They're all terrible. Must have a Ranco and then a titanium will be best of the lot.

I agree that a titanium heater with either a Ranco or a DC8 hooked up to an aquarium controller as a backup is the best choice.
I also use two smaller heaters rather than one large one for redundancy in case one fails.
