The difference between the 6 year and the 12 year is not only the warranty.
The sacrificial anode on the 12 year is more long lasting than on the six.
To me, I think it's worth the difference.

Water heaters are relatively inexpensive and generally fairly easy to
replace. I wouldn't bother with the extended warranty.
