I'm looking for some advice on when to replace a water heater.
Obviously
when it ruptures and water goes all over your basement is a good
time, but
prior to that, what is a good rule of thumb.

Ok, popular concensus is that gas water heaters last 10-14 years
whereas electrics last 20-40 years.

Why the difference?
(I thought tank life was primarily determined by anode condition)

Is there any difference between natural gas and lp gas tank life?
(Lp having lower btu rating, therefore cooler heating)
