I bought the Exide Select Orbital when my previous battery went, and it's been amazing. Even though I've had several times when the car lights were left on (don't ask) for a day or two, I couldn't detect the slightest drop in craking power upon return.
On top of that, the battery charges more quickly, doesn't corrode the terminals, and is lower maintenance than a regular battery. Once you've had to swap the battery once in the NSX, you'll understand why I wanted a battery I wouldn't have to change for a long LONG time.
