I plan on eventually stashing my battery in the trunk, at which time I will go for the Optima. However, I killed the original battery about 2 years ago (my roomie left my dome light on after dropping me off at the airport. It was left that way for almost a month). It would never hold a charge well after that so I replaced it.
I got a standard replacement from Checker (Autozone, Kragen, name your parts store) because of the warranty. The warranties are generally very long, long enough that you are almost guaranteed to get a free replacement at least once. I did the same thing when I had my F-150, and got like 1 or 2 free replacements when I had that. Its pretty nice just to go in there and swap them out!
