Anything you buy today will likely need replacing in < 10 years.
The old saying, they don't make them like they used to is a reality. My Rheem water heater is original to the house, from 1965. Plumber was here on something else and didn't believe it, but found the manufacture date on it, and it was made in 1965. It is electric and natural gas is not an option where I live.
My other house, built in 1971, has natural gas, and is on either the 4th or 5th water heater.
