Get the Red Top Optima, but get the one from Interstate. It's just a rebadged Red Top Optima with 3 years replacement warranty, and I think 5 years prorated warranty. Don't get the yellow top if you're planning to use it for engine starting.
I have an interstate battery up front but I also have an Optima Yellow Top in the trunk to power my system. I would say that if you really wanna get the best battery out there, the yellow top is the way to go, however I really don't know if it's that much better than the rest and worth the difference in price. I know that it is deep cycling, which means that it essentially lasts close to forever. So you can't go wrong with a yellow top, you might just be spending a bit more than you would on something that's almost as good.
