Interstate megatron plus or Bosch. Seen far too many Optimas die after only a year or two or 5. I'm in the minority though. Had a Bosch that lasted 8 years on an underdriven import alternator, same with an interstate megatron.
I'd use a Duralast/CSK battery before I'd use an Optima... strictly because if you have one go bad any autozone will replace it on the spot. I had one in my BMW and it was a great battery. no surprise though, because in the end, all those mentioned + Diehard + Walmart/OEM are all made by the same company, Johnson Controls.
the only way i'd ever have a n optima, would be if it was going inverted or laid down.
