Some time ago Consumer Reports cut open water heater to check the insides.

As I recall, the 9 or 12 year warranty heaters contained much better
insulation that the 6 year warranty.

If you decide to replace it...

With hot water heaters your much better off buyimng a longer warranty
heater with higher BTU output so you dont run out of hot water!

The price difference between a 34,000 BTU 40 gallon 6 year warranty
tank and a 50 gallon 75,000 BTU is TWICE the amount of available hot
water, better insulation, better drain valve, likely brass, longer
warranty and not a big price difference!
