I would go for the accessory circuit, because it's on when the key is turned back to the accessory position, and it's also on with the key is in the "on" position.

The ignition circuit is only active when the key is in the "on" position, so if you wanted to watch a movie with the truck parked, you couldn't turn the key back to accessory position to keep drain off the battery.
