Hi, I have an 80 gallon AO Smith electric hot water heater that was installed around 2003 by a previous homeowner. 15 years I think is a pretty good run for a hot water heater so I'm starting to explore replacement options. Looking to downgrade to a 50-55 gallon tank. I do not wish to go tankless at this time. From what I'm seeing there are really only 3 main brands. Rheem, AO Smith and Bradford White. And after looking at the reviews, they all are terrible ranging from defective models, to leaks, to poor customer service, to not honoring warranties. Just curious on anyone's experience with these or which one is the "least bad" out of the three. Thanks in advance.
