From my experience, they all have about the same longevity. The homeowner can do two things to extend the life of their unit:
(A) Flush the heater. Mineral buildup is a fact of life, and it reduces both the capacity and the ability of the unit to heat the water. Flushing it out on a yearly basis can help insure that you are getting the most out of your unit.
(B) Anodes. Each unit has a sacrificial anode screwed into the top of it. It's a long rod that is made from a metal alloy with a more "active" voltage (more negative electrochemical potential) than the metal of the tank it is protecting (the cathode). The difference in potential between the two metals means the sacrificial anode material corrodes in preference to the tank. This effectively stops the oxidation reactions inside the water heater.
Before you install the new heater, it would pay to remove the anode and coat the threads with Never-Seez compound. When it comes time to replace the anode, it will be a simple 15 minute job:

A plumber I know confided that a six year water heater and a 12 year unit are the same thing. Only difference is in the thickness and number of anodes. Sounds plausible......
Actually, Never Seez works really good for this. It won't harm anything, but she probably won't notice it for a while, and it will get EVERYWHERE. It's just graphite, though.
